Question

1. which formula represents the basic probability calculation?

a. p = total outcomes - unfavorable outcomes
b. p = number of favorable outcomes / total number of outcomes
c. p = 1/2 base height
d. p = a + b

Explanation:

Probability is calculated by dividing the number of favorable outcomes by the total number of outcomes. Option a is incorrect as it's not a valid probability formula. Option c is the formula for the area of a triangle. Option d is an undefined formula for probability. Only option b follows the basic probability concept.

Answer:

B. P = Number of favorable outcomes / Total number of outcomes
