Question

is an impossible event. 17. A spinner is shown below. Some of the events are listed below, when the spinner is spinned. Event A: The spinner lands on a multiple of 11. Event B: The spinner lands on a number less than 11. Event C: The spinner lands on a number more than 10. Which of the following statement is true about the three events? [CBSE Question Bank] (a) Probability of Event A is 1. so A is a sure event while the probabilities of Events B and Care 0. so they are impossible events. (6) Probability of Event B is 1, so B is a sure event while the probabilities of Events A and Care 0. so they are impossible events.​

Answer 1

Answer:

10" (and any subsequent words) was ignored because we limit queries to 32 words.

Answer 2

The answer is Probability of Event B is 1, so B is a sure event while the probabilities of Events A and C are 0, so they are impossible events.

• The spinner has numbers 1 to 10 on it.
• The probability of any event is given by $\frac{\text { favourable cases}}{\text {total cases}}$
• The total cases are 10 as the spinner can land on any number from 1 to 10.
• For Event A, the spinner must land on multiples of 11. As there are no multiples of 11 from 1 to 10, there are 0 favourable cases and hence the probability of Event A is 0.
• For Event B, the spinner must land on a number less than 11. As all numbers on the spinner are less than 11, the favourable cases are 10 and hence probability is 1.
• For Event C, the spinner must land on a number more than 10. As there are no numbers more than 10 on the spinner, there are 0 favourable cases and hence the probability of Event C is 0.

Hence Event B is a sure event while Event A and C are impossible events.
