When a person is selected at random from a very large population, the probability the selected person has green eyes 0.37. What is the probability that 4 people selected at random all have green eyes? Round your answer to 3 decimal places.

0.019

Step-by-step explanation:

Here, we want to calculate the probability that 4 people selected at random have green eyes.

The probability of having green eyes = 0.37

Now, we are selecting 4 people and we want to calculate the probability that all have green eyes

That would be;

0.37 * 0.37 * 0.37 * 0.37 = 0.01874161 which is 0.019 to 3 decimal places

∠acb = 8°

step-by-step explanation:

∠xba lies on the circle and is half the measure of the intercepted arc ax

hence

measure of arc ax = 2 × 42° = 84°

∠acb is outside the circle and is

∠acb = (arcab - arcax ), hence

∠acb = 0.5 (100 - 84) = 0.5 × 16° = 8°
