a die is thrown what is probality of getting a ) a prime number b) a even number
Answers
Answer:
a) 1/2 (50%)
b) 1/2 (50%)
Step-by-step explanation:
Possible outcomes = 1,2,3,4,5,6
No. of possible outcomes = 6
a) Prime numbers within possible outcomes = 2,3,5
No. of favoured outcomes = 3
Probability = 3/6
= 1/2
= 50%
b) Even numbers within possible outcomes = 2,4.6
No. of favoured outcomes = 3
Probability = 3/6
= 1/2
= 50%
When a die is thriwn once the sample space will be n(S)=6.
Now, let A be the case of getting a prime no. There are three prime nos. on a die ie. 2,3,5.
So Probability of getting a prime no. is P(A)=3/6=0.5
Now, there are 2,4 and 6- three even nos. and three odd nos. ie.1,3,5.
So,probability of getting an even no. and an odd no. is 0.5 and 0.5 repectively.
