Answer:
4/9
Step-by-step explanation:
From the picture :
The nine chips are : 1, 2, 3, 4, 5, 6, 7, 8, 9
Even chips = 2, 4, 6, 8
Probability = number of required outcomes / (number of total possible outcomes)
Probability of drawing a chip with an even number :
P(even number) = number of even chips / total number of chips
P(even number) = 4 / 9

Answer:
a.) .95
b.) The expected number of baskets is 10.50.
c.) 1.7748
Step-by-step explanation:
a.) This is a binomial distribution as there are two possibilities: makes a free throw or doesn't. This means that you can use the binomial function on a calculator to figure out the answer. Use the binomial CDF function on a calculator and the number of trials=15, probability of success=.7, lower bound=0, upper bound=7. Once you have evaluated the answer, .0500, it will need to be subtracted from1, as you want everything not included in this section. The answer to part a is thus 1-.0500=.95.
b.) The expected value is calculated by taking the total number of shots and multiplying it by the probability of making the shot: 15×.7=10.5 shots.
c.) The standard deviation of a binomial distribution can be calculated by the formula . Plugging in the numbers you get
=1.7748.
