<span>In a jar of ten beads; since 3 are blue; probability of picking a blue ball, B, = p(b) = 3/10. And P (of not picking a blue ball) ; p(b') = 7/10.
Since it occurs with replacement, probabilities doesn't change
Probaility of picking k blue balls from on n attempts is given by P_n(k)
P_n(k) = (n, k) p^(k) q^(n -k) where p and q are b and b' respectively.
P_5(2) = (5 , 2) (0.3)^(2) (0.7)^(5 - 2)
P_5(2) = 5C2 (0.3)^(2) (0.7)^(3) = 0.3087</span>

Each term contains a factor of a^2b. Factoring that out gives the answer above.
Answer:
I think you multiply because it is asking you how much money he earns in 5 hour, 6 hour and 8 hours .It also said that he gets paid $1 and 10 cent each hour.
Step-by-step explanation:
1.10 * 5=5.5
1.10 * 6=6.6
1.10 * 8=8.8
So, he earns $8.8

Answer:
y = 4x + 3
Step-by-step explanation:
The output of 3 at x = 0 tells you the y-intercept is 3.
The change of 4 from 3 to 7 for an input change of 1 from 0 to 1 tells you the slope is 4/1 = 4. Then the slope-intercept form of the equation is ...
y = mx + b . . . . . m = slope, b = y-intercept
y = 4x + 3
_____
It is pretty conventional to use y for the output variable and x for the input variable. Your rule could be ...
output = 4 × input + 3
