Question

which formula represents the basic probability calculation?
a. p = a + b
b. p = number of favorable outcomes / total number of outcomes
c. p = total outcomes - unfavorable outcomes
d. p = 1/2 base height

Explanation:

Probability is calculated by dividing the number of favorable outcomes by the total number of possible outcomes. Option a is an addition formula (not probability - related). Option c is an incorrect manipulation. Option d is the formula for the area of a triangle.

Answer:

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