Abox contains four red balls and eight black balls. two balls are randomly chosen from the box, and are not
replaced. let event b be choosing a black ball first and event r be choosing a red ball second.
what are the following probabilities?
p(b) =
p(rib) =
p(bnr)=
the probability that the first ball chosen is black and the second ball chosen is red is about percent.

the   probabilities will be following

P(B) =   8/12

P(RIB) =  4/11

P(BNR)=  8/33

probability that the first ball chosen is black and the second ball chosen is red is about  = 24 %

answer: what equations are there

step-by-step explanation:

x is greater than 5

step-by-step explanation:

2x+7 is greater than 17

    -7                           -7

2x is greater than 10

divide by 2 each side

x is greater than 5
