Question

A bag contains 7 red marbles, 3 blue marbles and 6 green marbles. If two
marbles are drawn out of the bag, what is the probability, to the nearest ioth
of a percent, that both marbles drawn will be red?

Answer 1

Answer:

42%

Step-by-step explanation:

figure probability of the first:

7+6+3=16

7/16=0.44

figure probability of the second:

6/15=0.40

find the average:

0.44+0.4=0.84

0.84/2=0.42

convert from decimal to fraction:

42%!
