Well, apologies if this is wrong but in my opinion, I think it's that The angles do not change. This is because the angles are alright staying in the same place. I don't understand much about angles but it makes the most sense to me.

allochka39001 [22]

Answer:

a. The probability of both balls are blue is $\frac{144}{1225}$ .

b. The probability of getting first red and second yellow ball is $\frac{18}{175}$ .

Step-by-step explanation:

It is given that the box contains 14 red balls,12 blue balls,and 9 yellow balls. The total number of balls is

$14+12+9=35$

The probability is defined as

$p=\frac{\text{Favorable outcomes}}{\text{Total number of outcomes}}$

Probability of getting red ball = $\frac{14}{35}$

Probability of getting blue ball = $\frac{12}{35}$

Probability of getting yellow ball = $\frac{9}{35}$

It is given that a ball is drawn at random and the color is noted and then put back inside the box. It means first event will not effect the probability of second event.

The probability of both balls are blue is

$\frac{12}{35}\times \frac{12}{35}=\frac{144}{1225}$

The probability of getting first red and second yellow ball is

$\frac{14}{35}\times \frac{9}{35}=\frac{18}{175}$
