greater than 5 (iii) an even number


2. A mathematics teacher wants to see, weather the new technique of teaching she applied after​

Answer 1

Answer:

1:1/2 2 :1/6 3 : 1/2

Step-by-step explanation:

probability formula no. of favourable outcomes / total no. of possible outcomes

Answer 2

Step-by-step explanation:

1,2,3,4,5,6 are the numbers present on a die.

(i) prime numbers present on a die are- 2,3,5.

Probability= No. of favourable outcomes/Total no. of events

Therefore probability of getting a prime number is 3/6

=1/2

[Remember that 1 is neither a prime number nor a composite number]

(ii) Probability of getting a number is 6/6

= 1

(iii)2,4,6 are the even numbers present on a die.

Probability=No. of favourable outcomes/Total no. of events

Therefore probability of getting an even number is 3/6

=1/2
