HELP ASAP;The tree diagram represents an experiment consisting of two trials.

1 answer:

6 0

Answer:

P(A) = 0.5

Step-by-step explanation:

Look from the tree root (left) and find A.

When you reach the first branch that shows A, the probability is on it's left, so

P(A) = 0.5

Presumably, whatever is drawn from Urn I is independent of what is drawn from Urn II. This means

$P(\text{red from Urn 1 AND red from Urn 2})=P(\text{red from Urn 1})\cdot P(\text{red from Urn 2})$

We have

$P(\text{red from Urn 1})=\dfrac4{10}=\dfrac25$

$P(\text{red from Urn 1})=\dfrac7{15}$

so the probability of drawing red balls from both urns is $\dfrac25\cdot\dfrac7{15}=\dfrac{14}{75}$

The answer is 4

Step-by-step explanation:

Because: (12x+5y)%3z is = [12(0.5)+5(6)]%3(3), which is (6+30)%9 = 4

I hope that this helps you to understand how to do it!
