Question

need help
Match the probability with the outcome if two number cubes are rolled 100 times.

an even number appeared on at least one cube 76 times

Answer 1

anybody

Answer 2

the probability an even number appears on "at least" one cube is \(\frac{3}{4}\)
is that more or less clear?

Answer 3

i need a percentage

Answer 4

@satellite73 not clear

Answer 5

nvm

Answer 6

that is not what i am asking
we can turn any number in to a percent, move the decimal place over two
the question is, it is clear that on any one throw, the probability you get at least one even number is \(\frac{3}{4}\)

Answer 7

so what are you saying

Answer 8

@dlearner think of it like this:
it is the same as flipping a coin, half even, half odd
(e, e, ) (e, o), (o, e) , (o,o)
three out of four times you get at least one even

Answer 9

what would it be in percentage then ????

Answer 10

oh k

Answer 11

you are not close to done
now you need to use the binomial with \(n=100, k=76, p=\frac{3}{4},1-p=\frac{1}{4}\)

Answer 12

then figure out the percentage by moving the decimal
that is not really much of the problem
