Answer:
Chi chi canhit a golf ball three times further than Rory.
Step-by-step explanation:
To compare the distance between the two golfers, we can set up a ratio:
Since the distance that Chi chi can hit the ball is 3:1 the distance that Rory can hit the ball, than Chi chi can hit the golf ball three times further. When reducing a ratio or fraction to lowest terms, you need to divide the numerator and the denominator by the same factor. Since 72 can be evenly divided by 24, we can divide both the numerator and the denominator by 24 to get 3:1.
We seems to be being asked the probability of rolling at least one four in fifty tries, which should be pretty high. As usual with "at least" questions, we write
p = P(at least one 4) = 1 - P(no fours at all)
The probability of a four on one roll is of course 1/6, so the probability for "not a four" is 1-1/6=5/6. We want the probability of a conjunction of 50 independent events: no four on the first roll and no four on the second roll and...
For a conjunction of independent events we multiply their probabilities. That's 5/6 times itself 50 times. So our answer is
If we need a decimal approximation, it's
