Answer:

0.25

0.65

Step-by-step explanation:

Looking at the question, we can see that we were not given the probability of selecting a yellow ball.

Hence the probability of this is;

1-0.35-0.4 = 1-0.75 = 0.25

The probability that the selected ball is yellow is 0.25

The probability that it is not red means it is either yellow or green

What this means is that we add the probability of yellow to the probability of green

= 0.25 + 0.4 = 0.65

Two numbers have a difference of 24. What is the sum of their squares if it is a minimum?
seraphim [82]
Let "a" and "b" be some number where:

a - b = 24

We want to find where a^2 + b^2 is a minimum.  Instead of just logically figuring out that the answer is where a=b=12, I'll just use derivatives.

So we can first substitute for "a" where a = b+24

So we have (b+24)^2 + b^2 = b^2 +48b +576 + b^2
And that equals 2b^2 +48b +576

Then we take the derivative and set it equal to zero:

4b +48 = 0
4(b+12) = 0
b + 12 = 0
b = -12

Thus "a" must equal 12.

So:
a = 12
b = -12

And the sum of those two numbers squared is (12)^2 + (-12)^2 = 144 + 144 = 288.

The smallest sum is 288.

aleksley [76]

Answer:

P(Y= 0) = 0.1

P(Y= 0) = 0.7

P(Y= 0) = 0.2

Step-by-step explanation:

Let Y be number of impurities that can be found in the well,

Let A denote the event that impurity A is randomly found in the well

Here Y can have three values i.e 0 , 1 and 2

✓It will take take the value of 0 when there is no impurity found in the well

✓It will take the value of 1 when when exactly one impurity vis found in the well

✓It will take the value of 2 when when both impurities vis found in the well
