9 x 6 = 54
54 - 4 = 50
50 + 5 = 55

Question:
Alfie tossed a paper cup in the air 150 times and recorded the side it landed on.
Right side up = 60 Upside down = 53 Side = 37
If Alfie tosses the paper cup 100 more times what is the expected number of times the cup will land on its side?
Answer:
The expected number of times the cup will land on its side is 25 times
Step-by-step explanation:
Given



Required
First, we calculate the probability of landing on side



Next, we calculate the expected value; E(x) using:

When tossed 100 more times:
n = 100 and P(x) = P(Side) = 0.247
So:


--- approximated
<em>Hence, it is expected that it will land on its side 25 times</em>
Answer:
<em>f = g/ g+1</em>
Step-by-step explanation:
Remove Parenthesis.
<em>fg - 1 x 5 = g - 1 x f - 1 x 5</em>
Cancel <em>-1 x 5</em> on both sides.
<em>fg = g - 1 x f</em>
Simplify <em>1 x f</em> to f.
<em>fg = g - f</em>
Add <em>f </em>to both sides.
<em>fg + f = g</em>
Factor out the common term <em>f.</em>
<em>f (g + 1) = g</em>
Divide both sides by <em>g + 1</em>
<em>f = g/ g + 1</em>
