Jeanine was making a baking. She used 1/2 cup of flour to make cookies and 2/3 cup of flour to make brownies. How much flour did
Fudgin [204]

Answer:

1 and 1/6 cups of flour

Step-by-step explanation:

We need the fractions to have common denominators so multiply 1/2 by 3 and 2/3 by 2 to get the common denominator of 6.

1/2 x 3/3 = 3/6

2/3 x 2/2 = 4/6

Add the two fractions

3/6 + 4/6 = 7/6 or 1 & 1/6

At the mall, buying a pair of shoes and buying a book are independent events.The probability that a shopper buys shoes is 0.20.
Goryan [66]

Answer: Probability that a shopper buys shoes and a book is 0.02.

Step-by-step explanation:

Since we have given that

Event A : Buying a pair of shoes

Event B:  Buying a book

Since A and B are independent events.

Probability that a shopper buys shoes i.e.

P(A) = 0.20

Probability that a shopper buys a book i.e.

P(B)=0.10

So, we need to find the probability that a shopper buys shoes and a book is given by

P(A\ and\ B)=P(A\cap B)=P(A).P(B)\\\\P(A\cap B)=0.20\times 0.10\\\\P(A\cap B)=0.02

Hence, Probability that a shopper buys shoes and a book is 0.02.
