Let x be the age of Ben and y be the age of Ishaan.
x= 4y... Equation (1)
x= y + 6... Equation (2)
Subtract the 2 equations
(1) - (2) : x-x= 4y - (y+ 6)
0 = 4y - y - 6
0 = 3y - 6
3y = 6
y = 2
So Ishaan is 2 years old
Substitute y = 2 in equation (1)
x = 4(2)
x = 8
So Ben is 8 years old and Ishaan is 2 years old.

Answer:

Step-by-step explanation:
If the total data set is 36 students, and you need to find out the probability that the randomly selected student studies both art and biology, you need to find the ratio:
Every 36 students there is 6
36 : 6
Divide both sides by 6:
6 : 1
So that means the probability is:
or 1.16 recurring
