It is known that 10% of adults can pass a fitness test. what is the probability that 17 adults in a sample of 100 adults pass this fitness test?
a. 0.9900
b. 0.0106
c. 0.1000
d. 0.0343

Option B

Step-by-step explanation:

We can use the binomial formula to solve this problem.

Where p is the probability of success, n is the sample size and x is the number of successes expected.

Note that in this case

(probability of an adult passing the fitness test)

Then we calculate the probability

45

step-by-step explanation:

(1,4) is on graph of f(x)

f(1) = 4

so 1/4 f(x)

1/4 f(1)

1/4. ×4

1

so point for function 1/4. f(x) is (1,1)
