Question

A box contains 5 red marble,8 white marble and 4 green marbles.One marble is taken out of the box at random.Wht is the probability that the marble taken out will b (1) white...(2)red....(3)not green....​

Answer 1

Answer:

• Probability of getting a white marble when taken out =  $\frac{8}{17}$
• Probability of getting a red marble when taken out  = $\frac{5}{17}$
• Probability of getting non green marble when taken out  = $\frac{11}{17}$

Step-by-step explanation:

Total number of marbles = 5 + 8 + 4 = 17 marbles

Probability = Number of outcomes

                     Total no. of outcomes

1. Getting a white marble when taken out-

Number of outcomes ( no. of white marbles ) = 8

Total number of outcomes ( Total no. of marbles ) = 17

∴  Probability of getting a white marble when taken out =  $\frac{8}{17}$

2. Getting a red marble when taken out-

Number of outcomes ( no. of red marbles ) = 5

Total number of outcomes ( Total no. of marbles ) = 17

∴  Probability of getting a red marble when taken out  = $\frac{5}{17}$

3. Getting a non green marble when taken out-

Number of outcomes ( no. of non green marbles ) = 5 + 8 = 13

Total number of outcomes ( Total no. of marbles ) = 17

∴  Probability of getting non green marble when taken out  = $\frac{11}{17}$

hope it helps you..
