Question

white nor black
There are 30 cards numbered from 1 to 30. One card is drawn at random. Find the
probability that the number of the selected card is not divisible by 3.
​

Answer 1

Answer:

P( Card not divisible by 3) = 0.66

Step-by-step explanation:

We have been given:

No of Cards(from 1 - 30) = 30

No of cards not divisible by 3 = 20

We know

P(E) = $\frac{No. of possible outcomes }{Total no of outcomes}$

P( Card not divisible by 3) = $\frac{Cards not divisible by 3}{Total no of cards}$

                                            =  $\frac{20}{30}$

                                            =$\frac{2}{3} =0.66$

P( Card not divisible by 3) = 0.66   Ans
