You roll four six-sided die. Find the probability that exactly three of the dice are odd.

s344n2d4d5 [400]

Answer:

3/8

Step-by-step explanation:

There is a 1/2 probability one die will be odd because 1, 3, and 5 are the only possible odd numbers.

Since you want 3/4 of the dice to be odd, you multiply 1/2 by 3/4 to get 3/8.

I believe it is 3/8.

Ravi ordered some books online and spent a total of $89. Each book cost $5 and he paid a total of $4 for shipping. How many book

Katyanochek1 [597]

Answer:

He bought 17 books.

Step-by-step explanation:

Given that:

Total money spent = $89

Cost of each book = $5

Shipping price = $4

We have to find, Total number of books

So if the number of books be represented by b, the equation will become:

Cost of one book * total number of books + shipping price = total money

Putting values we get:

5*b + 4 = $89

By simplifying:

5*b = 89 - 4

5*b = 85

Dividing both sides by 5 we get:

b = 17

So the total number of books bought is 17.

i hope it will help you!
