The expected outcomes less than 4 is the average of the outcomes
We would expect to get a number less than four out of 200 trials 100 times
<h3>How to determine the expected number of rolls?</h3>
The sample space of a number cube is:
S = {1,2,3,4,5,6}
There are 3 outcomes less than 4.
So, the probability of obtaining a number less than 4 is:
p = 3/6
This gives
p = 0.5
In a roll of 200, the expected outcomes less than 4 is:
E(x) = 0.5 * 200
This gives
E(x) = 100
Hence, we would expect to get a number less than four out of 200 trials 100 times

This is a tricky question because you might use the ratio and proportion method. However, there are 3 terms involved. To cut it down to 2, let's lump the profit rate. The solution is as follows:
10:5/2::8:x/3
Solving for x,
20/5 = 24/x
x = 24(5)/20 = 6
<em>Hence, it will earn 6 dirhams of profit.</em>
Answer:
128
Step-by-step explanation:
24 + 24 + 40 + 40= 128
Y = kx
so
k = y/x
<span> (4, 0.45) ; 0.45 / 4 = .1125 ...NO
(7.2, 4) ; 4 / 7.2 = 0.5556(5 repeat)...NO
(4, 7.2) ; 7.2 / 4 = 1.8 ...YES
(0.45, 4) ; 4 / 0.45 = 8.89(8 repeat) ....NO

answer
C. (4, 7.2)
