Two numbers with factors 2,3,5 are 30 and 60.
when we multiply 2 x 3 x 5 = 30
we get answer 30 and then again multiply with the number that is greater than 1 is 2 and then we get 2 x 2 x 3 x 5 = 60
So the first two numbers with factors 2, 3 and 5 are 30 and 60.
It should be C
Have a good day!!
The chance of One heads occurring is 1/2.
The chance of the second occurring separately is 1/2 as well. Joint together, it is 1/2x1/2: which is 1/4.
So your answer is 1/4 chance
I hope this Helps!
