Probability is all about multiplying fractions.
The first fraction is the probability of picking a girl.. so how many of the 12 total children are girls. (8/12)
The second fraction is the probability of picking a boy.. so how many of the 11 remaining children are boys. (4/11)
8/12 X 4/11 = 8/33 -> this isn't even an option but I'm like 10000% this is the right answer..
I started off this answer feeling so confident lol. good luck.
the given expression is,
5x - (x +1) = 5 - 2x
5x - x - 1 = 5 -2x
4x + 2x = 5+1
6x = 6
x = 6/6
x = 1
thus, the answer is x = 1
X= 23 degrees
To find this you first add up 124 and 33 which equals 157. Then you would subtract 157 from 180 because all triangles equal 180.
