Answer:
5 jumps
Step-by-step explanation:
Personally I would write it out, although there surely is a formula for it.
3 fall to 2 - 5 fall to 4 - 7 fall to 6 - 10 fall to 9 - 12.
This makes 5 jumps, since once he is out he won't fall back in.
Answer: 2/15
Step-by-step explanation: To find this compound probability, first note that there is no replacement.
The probability of drawing the first white token is 4/10 or 2/5.
The probability of drawing the second token is 3/9 or 1/3 because one white token has already been taken away. Now, multiply 2/5 by 1/3 to get the answer, which is 2/15
To find the reciprocal, flip the fraction!
Y=kx so 3 would be the constant
Using Quadratic formula,
x = 0.386, -3.886
