A fair coin is tossed, and a marble is chosen from the bag whose contents are shown below. 3 red marbles, 3 blue marbles, and 4 green marbles. What is the probability of the coin landing heads up and a blue (B) marble being randomly selected? StartFraction 3 over 20 EndFraction StartFraction 1 over 6 EndFraction StartFraction 4 over 5 EndFraction StartFraction 5 over 6 EndFraction

The probability of the coin landing on heads is 1/1 which is 1 and the probability of the blue marble is 7/3.

Step-by-step explanation:

the probability of the coin, E=1 from[HH,HT]

                                            S=1 so P=1/1=1

the probability of all of the marbles=3+3+4/3=10/3

so to get the probability of the blue marble=10/3-3/3=7/3

sorry, i'm new here and i'm just trying to figure this out. try quizlet. rate 5* you!

first one because it can't have a fraction in it
