Let a and b be events in a probability space ( ; p) with 0 < p(b) < 1. Use the de nition of conditional probability and the additivity of probability to show that p(acjb) = 1 ������ p(ajb).

1 x=22.52

2: 65/39=604+39x

65x-39x=604

26x=604

x=604/26

×=23.23

4

step-by-step explanation:

6 (donuts) divided by 3 is 2.

so 2/3 means 2 times 2, which is 4/6.

you get two and your friend gets four.

i hope this answer you! if you have any further questions or concerns, feel free to ask! : )

x = -4

step-by-step explanation:

- 20 - 4(x + 3) = 4x

=> -20 - 4x - 12 = 4x

=> - 32 -4x = 4x

=> -32 = 4x + 4x

=> - 32 = 8x

=> -32/8 = x

=> -4 = x
