Question

a dice is thrown 6 times what is the probability that it is a prime number​

Answer 1

Answer:

n(s)=36

Step-by-step explanation:

2,3,5 are prime no.

so when dice is thrown 6 times

then prime nno.will be 6 times

so prime no.=18

n(E)=18

p(getting prime no.)=n(E)/n(s)

=18/36

=1/2

Answer 2

Step-by-step explanation:

The prime numbers in a dice = 2,3,5.

Therefore, there are three prime numbers in a dice.

Therefore, the probability = Possible outcomes/ Total outcomes

= 3/6

= 1/2.

Now during six times the total number of outcomes = 6×6=36 outcomes.

And total number of possible outcomes = 3× 6 = 18

Therefore, probability of getting a prime number when dice is thrown 6 times = 18/36 = 1/2.

So, your answer is 1/2.

Hope this helps you understand my friend
