The probability that the first horse wins is 2/7. The probability that the second horse wins is 3/10. Since the events that the first horse wins and the second horse wins are shared exclusive, the probability that either the first horse or the second horse will win is :
2/7 + 3/10= 41/70
Hope this is correct.
<u><em>Answer:</em></u>
The height of the stack =
in
<u><em>Explanation:</em></u>
We are given that Jean stacks a dictionary on top of a novel.
This means that the total height of the stack will be equal to the height of the dictionary added to the height of the novel.
<u>From the givens, we have:</u>
height of dictionary =
in
height of novel =
in
<u>Now, adding the two height, we will have:</u>
Total height of stack = height of novel + height of dictionary
Total height of stack =
in
