(a)
The probability distribution is as follows:
X Frequency P(X)
0 8 0.042
1 10 0.052
2 33 0.173
3 53 0.277
4 43 0.225
5 25 0.131
<u>6 19 0.099
</u>
<u> 191 1.000
</u>
(b)
Construct the histogram in Excel.
The histogram is approximately symmetric as maximum data is collected in the middle.
Answer:
26
Step-by-step explanation:
When you flip two coins, you can have 4 different outcomes:
HH
HT
TH
TT
All outcomes are equally likely, but notice that if you do not keep track of which coin is which, you will get 1/4 of the flips to be both heads, 1/4 of the flips to be both tails, and 1/2 of the flips to be one heads and one tails.
p(both heads) = 1/4
With 105 flips, the expected number of both heads is
105 * 1/4 = 26.25
Answer: 26
Answer:
24 Units Cubed
Step-by-step explanation:
Start with the face of your 3D shape, which has a length/width of 3 units and a height of 4 units. Then look at the visible side of your figure, in this case it is the right side. You can see it's width/length of 2 units, so multiply 4x3x2, and in this case 4x3=12 and 12x2 is 24. making your answer 24 units cubed.
