Answer:
Step-by-step explanation:
√a+√b=√(a+b)
squaring
a+b+2√a√b=a+b
or 2√a√b=0
which is possible only if a=0 or b=0
Both a and b can't be zero as a≠b

Step-by-step explanation:
The probability distribution in the second row simply shows the probabilities for each number in the first row.
To find the probability that x is between -5 and 5, you can add the probabilities -5 < x < 5.
P(-5) = 0.15
P(0) = 0.05
P(5) = 0.1
0.15 + 0.05 + 0.1 = 0.3
