Steve and sasha are brother and sister. steve has three times as many sisters as brothers, and sasha has as many brothers as sisters. how many boys and girls are there in this family?

5

Step-by-step explanation:

Using b and g to refer to the boys and girls in the family, we have that

For Steve: 3(b-1)=g (since his brothers are b-1, since he does not count himself)

For Sasha: g-1=b (the same reasoning as before)

We can the calculate that

g=b+1

3(b-1)=b+1

3b-3=b+1 => 2b=4  => b=2

g=2+1=3

There 3 girls and 2 boys in the family, meaning 5 children in total.

15%

step-by-step explanation:

use the table and count the number of guesses that has two correct answers.

the following are two correct answers

10010, 01100, 11000

a total of 3 numbers having 2 correct guesses out of 20 questions.

probability of getting 2 correct guesses = the number of questions getting 2 correct answers / total number of questions.

= 3/20

to convert it into percent multiply by 100, we get

= 3/20 * 100

= 15%

the answer is 15%
