two dice are thrown simultaneously. probability of getting a prime number on both dice is?
Answers
Answer:
let the event be getting a prime number
no: of possible outcomes = 9
total no: of favourable outcomes = 36
P(E) = no: of possible outcomes/total no: of favourable outcomes
9/36
therefore the probability of getting a prime number = 9/36
(1,1) , (1,2) , (1,3) , (1,4) , (1,5) , (1,6)
(2,1) , (2,2) , (2,3) , (2,4) , (2,5) , (2,6)
(3,1) , (3,2) , (3,3) , (3,4) , (3,5) , (3,6)
(4,1) , (4,2) , (4,3) , (4,4) , (4,5) , (4,6)
(5,1) , (5,2) , (5,3) , (5,4) , (5,5) , (5,6)
(6,1) , (6,2) , (6,3) , (6,4) , (6,5) , (6,6)
I think this is the answer...............I hope it helps you
Answer:
Probability of getting prime number on both dice when two dice are thrown simultaneously is 1/4.
Explanation:
Explanation:Probability:
- Probability is the measure of occurrence of a random event..
Formula:
- Probability of an event = No. of favourable outcomes /Total no. of events.
Event:
- When two dice are thrown simultaneously Total no. of outcomes =36
- Here, No. of favourable outcomes = getting prime number on both the dice.
- When two dice are thrown simultaneously then the possibilities of getting prime numbers on both dice are given below
(2,2) (2,3) (3,2) (3,3) (2,5) (5,2) (5,5) (3,5) (5,3)
So,
No. of favourable outcomes = 9
Probability of an event = no. of favourable outcomes/ Total no. of outcomes
Hence, Probability of an event = 9/36 = 1/4
