In a group of twelve people, four had been selected for a transfer. If two of the twelve are selected, what is the probability that both of those selected are selected for a transfer?

1/11

Step-by-step explanation:

The probability the first person has been selected for transfer is 4/12.

The probability the second person has been selected for transfer is 3/11.

So the probability of both is 4/12 × 3/11 = 1/11.

c.35

step-by-step explanation:

8+13=21

21+8=29

29+6=35

b is 38 degrees.

a is 52 degrees.

this is because if b is 38 and a is 14 degrees more than b than 38+14=52 and 52+38=90 degrees. hope this .
