Please see pic, I'd solved in it.
.5 * .5 *.5 = 1/8
-
-
the probability to have head is .5 so the probability of tails 1-.5
-
then the first time is head
the second time is head
the third time is tail
so
.5 * .5 *.5 = 1/8
If U={1,2,3,4,5) and A={2,4) then A' should be
Ans» d.{1,3,5}
Answer:
B
Step-by-step explanation:
If the diameter of sphere B is 42, that means the radius is half, so it is 21.
The question is asking what multiplied by 24 is 21, or 21 divided by 24. 21/24 can be simplified to 7/8.
