P(Both) = 0.1792
Givens
The total number of roles = 100
Total number of heads = 56
Number of times rolled a four = 32 [check this for me].
Set up the probabilities.
P(H) = 56/100
P(4) = 32/100
P(H)*P(4) = P(Both)
Substitute and solve
P(Both) = 56/100 * 32/100 = 1792/10000
P(Both) = 112/625 because there are many cancellations. Or you could just express it as 0.1972
Answer:
He has to work at least 25 hours to make $1,250 for his trip. (plus the $500 that he already saved)
Step-by-step explanation:
He currently has: $500 (I don't know if this $500 is counted in the $1,250. But I'm going to put it in $1,250)
So, 1,250 - 500 = 750
He only has to make $750 more to reach $1,250
Works and makes $30 an hour.
30
x25
--------
750
500 + 750 = 1,250
