Question

"Question 2 When a die is thrown, list the outcomes of an event of getting (i) (a) a prime number (b) not a prime number (ii) (a) a number greater than 5 (b) a number not greater than 5

Data Handling Page 87"

Answer 1

Outcomes= 1,2,3,4,5,6
Prime no.s=2,3,5
Not a prime no.= 1,4,6
P=probability
Formula: p(event) = favourable no.of outcomes/total no.of outcomes


Q2 solutions
1) P(prime no)=3/6=1/2
2) P(non-prime no ) = 3/6=1/2
3) P(no. greater than 5) = 1/6
4) P(no.not greater than 5) = 5/6

Answer 2

Event:

A Possible outcome or combination of outcomes is called event.

==========================================================

Solution:

(i) Outcomes of event of getting a prime number are 2, 3, 5 

Hence, these are the outcomes of an event of getting a prime number (2,3,5)

(ii) Outcomes of event of not getting a prime number are 1, 4 and 6.

Hence, these are the outcomes of an event of not getting a prime number (1,4,6)

(b)

(i) Outcomes of event of getting a number greater than 5 is 6, which comes on the face of the dice.

Hence, these are the outcomes of an event of getting a number greater than 5 is 6, 

(ii) Outcomes of event of not getting a number greater than 5 are 1, 2, 3, 4 & 5 

Hence, these are the outcomes of an event of not getting a number greater than 5 are 1, 2, 3, 4 & 5
