Question

a jar has one blue and 9 Green Marbles in it what is the probability of drawing a blue marble​

Answer 1

since , jar contains total of {9+1}=10 balls

so n{s}=10

For drawing blue ball, n{e]=1

probability of getting one blue ball is

                                                               

                                                           P{E}=n{e}/n{s}

                                                                P{E} =1/10

Answer 2

The probability of drawing a blue marble​ is$\frac{1}{10}$

Step-by-step explanation:

Number of blue marbles = 1

Number of green marbles = 9

Total number of marbles = 1+9 = 10

Probability of getting an event = $\frac{\text{Favorable event}}{\text{Total events}}$

Probability of getting an event =$\frac{\text{No. of blue marble}}{\text{Total marbles}}$

Probability of getting an event = $\frac{1}{10}$

Hence  the probability of drawing a blue marble​ is$\frac{1}{10}$
