Answer:
The probability is 1/18.
Step-by-step explanation:
There are 10 balls in total. Let's start with the probability of just the green. There is 1 green ball.out of 10 balls total, so the probability of pickin just the green one would be 1/10. Since we aren't replacing the balls after we choose them, the total number of balls is now 9. now the probability of picking one yellow ball out of the nine balls left is 5/9 because there are 5 yellow balls. To get the probability of the green and yellow balls picked, we multiply the individual probabilities to get the actual probability of choosinf one green and one yellow ball without replacement. So multiply 1/10×5/9= 5/90, simplified to 1/18.
11) ∠Q+∠R+∠S=180°
let ∠Q=∠S=x
x+58+x=180
2x=122
x=61
since∠Q=∠S=x
∴∠Q=∠S=61°
12) M+N+P=180
x+2x-1+2x+1=180
5x=180
x=36
∴m=36
n=2x-1
=72-1
=71
p=2x+1
=72+1
=73
13) her answer is not reasonable because they are angles on a straight line and sum of angles on a straight line =180 and 86+86≠ 180.
