(2r-1)(r-1)
=2r(r-1) -1(r-1)
= 2r^2-2r-r+1
=2r^2-3r+1

There are four slices of pepperoni pizza and three slices of veggie pizza sitting on the counter. what is the probability of ran
Otrada [13]

Answer:

The probability of randomly choosing a slice of veggie pizza is 3/7

Step-by-step explanation:

Probability is the measure of uncertainty of any event. It is the ratio of number of favorable outcomes to the total number of possible outcomes. That is,

Probability, P(A) = (Number of a Favourable outcome) / (Total number of possible outcomes).

From the question,

There are four slices of pepperoni pizza and three slices of veggie pizza, this means

Total number of favourable outcomes = 4 + 3 = 7

The favourable outcome is the veggie pizza, therefore

Number of favourable outcome = 3

Hence,

Probability P (A) = 3 ÷ 7

P(A) = 3/7

The probability of randomly choosing a slice of veggie pizza is 3/7
