PLEASE HELP!!!


41. A bag contains 13 red marbles, 12 green marbles and 5 blue marbles. If you mix up the
marbles and pull one out at random, what is the probability that it will be blue? (Answer,
of course, as a fraction in lowest terms.)

Respuesta :

Answer:

Number of red marbles = 13

Number of green marbles = 12

Number of blue marbles = 5

Total Number of marbles = 13+12+5

Total Number of Marbles = 30 marbles

[tex] \bf \: probability \: of \: blue \: marbles \: = \frac{number \: of \: blue \: marbles}{total \: number \: of \: marbles} [/tex]

[tex]\sf \dashrightarrow \: probability \: of \: blue \: marble = \frac{5}{30} \\ \\ \sf \dashrightarrow \: probability \: of \: blue \: marble = \cancel \frac{5}{30} \\ \\ \sf \dashrightarrow \: probability \: of \: blue \: marble = \frac{1}{6} [/tex]

So, the probability of blue marbles would be ⅙ .

Answer:

1/6 chance of getting blue

Step-by-step explanation:

find your total (30) that will be your denominator

the number of blue marbles will be your numerator (5)

then simplify 5/30 to 1/6
