Algebra -> Probability-and-statistics-> SOLUTION: A natural number is selected at random from 1 to 100.Find the probability of (a) getting a multiple of 4, (b) getting a number that is not a multiple of 4. Can someone plz he Log O Experiment 2 illustrates the difference between an outcome and an event. A single outcome of this experiment is rolling a 1, or rolling a 2, or rolling a 3, etc. Rolling an even number (2, 4 or 6) is an event, and rolling an odd number (1, 3 or 5) is also an event. In Experiment 1 the probability of each outcome is always the same The number of ways to choose 5 out of the 6 winning numbers is given by 6 C 5 = 6 and the number of ways to choose 1 out of the 42 losing numbers is given by 42 C 1 = 42. Thus the number of favorable outcomes is then given by the Basic Counting Rule: 6 C 5 × 42 C 1 = 6 × 42 = 252. So the probability of winning the second prize i

For instance, if the player selects only 1 number, then he or she wins if this number is among the set of $20,$ and the payoff is $\$ 2.20$ won for every dollar bet. (As the player's probability of winning in this case is $\frac{1}{4},$ it is clear that the fair payoff should be $\$ 3$ won for every $\$ 1$ bet. Given a probability of Reese's being chosen as P(A) = 0.65, or Snickers being chosen with P(B) = 0.349, and a P(unlikely) = 0.001 that a child exercises restraint while considering the detriments of a potential future cavity, calculate the probability that Snickers or Reese's is chosen, but not both

a whole number from 1 to 40 is chosen at random

Answer: Since you carried out 67 trials and the number of 3s was 0, then the empirical probability of getting a 3 is 0/67 = 0, so the probability of not getting a 3 is 1 - 0 = 1. In a greater number of trials there may be an outcome of a 3 so the odds of not getting a 3 would be less than 1 Note that there are 4 multiples of 9 in the range 1 to 40, namely 9, 18, 27, 36. So the probability of the mover picking a box of one of these multiples is 440. Therefore, by the complement rule, the probability of not picking a box numbered with a multiple of 9 is 1−440=3640=9/10 Find the probability that (a) the sum is not 4 and (b) the sum is greater than 5.

Probability - four random integers between 0-9, that not

You choose a number with 3 digits from 0 to $9 ;$ the state chooses a three-digit winning number at random and pays you $\$ 500$ if your number is chosen. Because there are 1000 numbers with three digits, you have probability 1$/ 1000$ of winning 9. not rolling a number less than 5 _____ 10. A tire manufacturer checks 80 tires and finds 6 of them to be defective. a. What is the experimental probability that a tire chosen at random will be defective? _____ b. The factory makes 200 tires. Predict the number of tires that are likely to be defective PROBABILITY 1. In the first session to see if you have ESP, the psychologist has 20 cards with the numbers 1 to 20 written on them. (a) How many different combinations of cards is possible if she holds 4 cards up facing her and one at a time, you have to write down the numbers that she is looking at in order

What is the probability that a number selected at random

Label the four faces of a tetrahedral die with 1, 2, 3, and 4 spots. (a) Give the probability model for rolling such a die and recording the number of spots on the down-face. Explain why you think your model is at least close to correct. Let X = number of spots. Then P(X = 1) = P(X = 2) = P(X = 3) = P(X = 4) = 0.25 The probability \(p\) of a success is the same for any trial (so the probability \(q = 1 − p\) of a failure is the same for any trial). Binomial Probability Distribution a discrete random variable (RV) that arises from Bernoulli trials; there are a fixed number, \(n\), of independent trials
