Question

there are boards numbered 3 to 53 in a box. 1 board is selected randomly. find out the probability of getting multiple of 7​

Answer 1

Step-by-step explanation:

Boards numbered: 3 to 53

Total cards = 53 - 3 = 50             [ card are numbered continuous after 3 ]

Favourable outcome as multiple of 7 = 7, 14, 21 ......... 49

Total Favourable outcome = 7            [ 53 ÷ 7,  q = 7, so the set contains

                                                            7 cards numbered as multiple of 7 ]

Probability of getting a multiple of 7 = 7 / 50         ( Ans)

HOPE THIS IS HELPFUL !!! : )
