On a given school day, the probability that Nick oversleeps is 48% and the probability he has a pop quiz
sasho [114]

Answer:

0.12

Step-by-step explanation:

Independent events are when probability of one event happening doesn't affect the probability of the other event happening.

Also,

In probability "AND" means "multiplication" and "OR" means "addition".

The question asks for probability that Nick oversleeps "AND" has pop quiz. So we need to multiply the individual probabilities (since independent, they have no affect on each other).

P(Nick oversleeps) = 0.48

P(pop quiz) = 0.25

Thus,

P(Nick oversleeps AND pop quiz) = 0.48 * 0.25 = 0.12

Calculate the Theoretical probability of the following experiments.
Nataliya [291]

The probability that she will NOT take out an orange, then an apple, and finally a grapefruit in that order is 0.2917.

<h3>What is Probability?</h3>

Probability helps us to know the chances of an event occurring.

\rm Probability=\dfrac{Desired\ Outcomes}{Total\ Number\ of\ outcomes\ possible}

A.) The probability that she will NOT randomly take out two oranges in a row,

Probability = 1 - (5/12)² = 0.8264

B.) The probability that she will NOT randomly take out two grapefruits in a row,

Probability = 1 - (4/12)² = 0.8264 = 0.8889

C.) The probability that she will NOT randomly take out two apples in a row,

Probability = 1 - (3/12)² = 0.8264 = 0.9375

D.) The probability that she will NOT take out an orange, then an apple, and finally a grapefruit in that order,

Probability = (7/12) × (9/12) × (8/12) = 0.2917
