Answer:
a) P = 0.125
b) It is not necessarily true
Step-by-step explanation:
a. If the coin was fair, the probability of obtaining head would be 0.5, and each launch of the coin would be an independent event.
Remember that if two events A and B are independent, then:
P(A∩B) = P(A)P(B)
Therefore, the probability that Caitlin would get heads on all three flips is:
P(A∩A∩A) = P(A)P(A)P(A) = 0.5*0.5*0.5 = 0.125
b) It is not necessarily true, because there exist a probability associated to this event and it means that this situation can occur although the coin was fair.
Rachel says that when she ran 115 yards she went farther than Beth who only ran 227 ft. Rachel is correct
<u>Solution:</u>
Given that , Rachel says that when she ran 115 yards she went farther than Beth who only ran 227 ft.
We have to remember that when 1 yard equals 3 ft.
Yes, what Rachel said is correct, let us see how it became correct
In normal view, 115 < 227 but here units are different.
Remember that, for any comparison between two things, we have to take the things in same units.
<em><u>Let us convert 115 yards to feet:</u></em>
![\begin{array}{l}{115 \text { yards }=115 \times 1 \text { yard }} \\\\ {115 \text { yards }=115 \times 3 \text { feet }=345 \text { feet }}\end{array}](https://tex.z-dn.net/?f=%5Cbegin%7Barray%7D%7Bl%7D%7B115%20%5Ctext%20%7B%20yards%20%7D%3D115%20%5Ctimes%201%20%5Ctext%20%7B%20yard%20%7D%7D%20%5C%5C%5C%5C%20%7B115%20%5Ctext%20%7B%20yards%20%7D%3D115%20%5Ctimes%203%20%5Ctext%20%7B%20feet%20%7D%3D345%20%5Ctext%20%7B%20feet%20%7D%7D%5Cend%7Barray%7D)
Now, 345 feet > 227 feet
Which means, Distance covered by Rachel > Distance covered by Beth
Thus Rachel ran more than Beth. Hence, Rachel is correct.
