QUESTION :-

➙A spinner whose sectors are painted in the seven spectrum colours (VIBGYOR) is spun 35 times. How many number of times do you expect the pointer to point at the red sector ?

ANSWER :-

➙ 5 times

STEP BY STEP EXPLANATION :-

Possible outcomes are Violet, Indigo, Blue, Green, Yellow, Orange, Red.

➙Total number of possible outcomes = 7

Number of red sector =1

Thus, the number of favourable outcomes =1

➙ P (getting a red sector) = 1/7

In 35 times, the number of times the pointer is likely to point at the red sector

= 1/7 x 35 times = 5 times

Answer 2

Answer:

5 times

Possible outcomes are Violet, Indigo, Blue, Green, Yellow, Orange, Red.

➙Total number of possible outcomes = 7

Number of red sector =1

Thus, the number of favourable outcomes =1

➙ P (getting a red sector) = 1/7

In 35 times, the number of times the pointer is likely to point at the red sector

= 1/7 x 35 times = 5 times
