A bag contains 3 pink gumballs, 4 red gumballs, and 2 green gumballs. Find the probability that a red gumball is drawn if there
fgiga [73]

Answer:

0.99

Step-by-step explanation:

Given,

Pink gumballs = 3,

Red gumballs = 4,

Green gumballs = 2,

So, total gumballs = 3 + 4 + 2 = 9,

Thus, total ways of selecting 5 gumball = ^9C_5

=\frac{9!}{5!4!}

=\frac{9\times 8\times 7\times 6}{24}

=9\times 2\times 7

=126

Also, the total ways of selecting no red gumballs = ^4C_0\times ^5C_5

= 1 × 1

= 1

So, the probability of no red gumballs in 5 drawn

=\frac{1}{126}

Hence, the probability that a red gumball is drawn if there are 5 drawings

= 1 - probability of no red gumballs

=1-\frac{1}{126}

=\frac{125}{126}

≈ 0.99
