In a group of 44 students, 11 study both Art and Biology. 10 study Biology but not Art. 2 study neither subject. Given that a randomly selected student studies Art, what is the probability the student studies Art and Biology?

1/4 or 0.25

Step-by-step explanation:

Probability is the ratio of the number of possible outcome to the number of total outcome.

Given that 11 study both Art and Biology and there are 44 students in class. To determine the probability that a student picked at random studies Art and Biology,

the number of possible outcome = 11

number of total outcome = 44

the probability the student studies Art and Biology

= 11/44

= 1/4

= 0.25

1. is 4 and 2. is 3

step-by-step explanation:

so if you look at the first one you see that 1 is to 4 and 2 is to 8 and so on, so you can see for every 1 there is a times 4 so if it were 3 then it would be 3*4 and it is 12

for number 2 it is 3 because 1 is to 3 and 2 is to 6 so for every 1 there is 3 so if it were 3 then there would be 3*3 = 9

cpctc makes it so that corresponding parts of the triangle you proved to be equal are equal, the other options aren't part of the part of the triangles you proved to be equal.
