9 sleeves for 22.99

Step-by-step explanation

The first pack has a unit rate of $11.49/ 4 balls

Michael wants to take French or Spanish, or both. But classes are closed, and he must apply and get accepted to be allowed to en
Brums [2.3K]

Answer:

80%.

Step-by-step explanation:

Given the following probabilities:

  • P(Micheal Being admitted to French), P(F)=50%
  • P(Micheal Being admitted to Spanish), P(S)=50%

In Probability Theory, when we have BOTH , we mean the intersection of the probabilities. Therefore:

  • P(Micheal Being admitted to BOTH French and Spanish), P(F \cap S)=20\%

We want to determine the probability that he will be enrolled in either French or Spanish (or possibly both).

Probability of either A OR B =P(F \cup S)

From Probability Theory:

P(F \cup S) = P(F)+P(S)-P(F \cap S)\\P(F \cup S) =50+50-20\\P(F \cup S) =80

The probability that he will be enrolled in either French or Spanish (or possibly both) is 80%.
