(2!/(2-2)!*2!)*.5^2*(1-.5)^0(2!/(2-2)!*2!)*.5^2*(1-.5)^0
this answer is .25 or 25% not sure why it giving me the answer of 1.
Split it in two halves like this:
[((2!)/((2 - 2)!)×2!)×0.5^2 (1 - 0.5)^0] * [((2!)/((2 - 2)!)×2!)×0.5^2 (1 - 0.5)^0]
1 * 1
==1 * 1 ==1 - the way you have it written, it does come out as 1. You have to check your parentheses. To get the result to come out as 25% ==0.25, you have to get the 2 sides to equal: 0.50 * 0.50 ==0.25
