Ok, remember that if you had 1/2 times 3/4 that (1 times 3)/(2 times 4)
what you do is mutliply top number with top number and bottom number by bottom numer
remember that 2=2/1 so
2/1 times 3/8=
2 times 3=6
1 times 8=8
2/1 times 3/8=6/8
According to order of operations rules, exponentiation must be done first. Thus, we have
(3^2)*(3^2) = (9)(9) = 81.
Alternatively, note that there's only one base (3) here, even tho' it shows up more than once. So, 3^2*3^2 = 3^(2+2) = 3^4 = 81.
The intersection of two sets A and B is defined as the set composed by the elements appearing in both A and B.
So, the intersection is

Because all the other numbers do not belong to both sets:
- 2, 3 and 7 belong to A alone
- 13, 15 and 17 belong to B alone
- 5 and 11 belong to both A and B
Discrete random variable as we count the number of free dash throw attempts and we dont measure them (continuous)
