In a probability experiment, Karen flipped a coin 84 times. The coin landed on heads 36 times. What percentage of the coin flips

hodyreva [135]

Answer:

57.1%

Step-by-step explanation:

We know that a coin has only two sides, heads or tails. Therefore if of the 84 times, 36 times he fell in heads, the other times he fell in tails.

84 - 36 = 48 times fell in tails.

Therefore to calculate the percentage that fell in tails, it would be the ratio between the number of times it fell in tails and the total number of experiments:

48/84 = 0.571, and that is 57.1%

Which means that 57.1% of the times the coin was thrown fell into tails.

Given that the commuter used public transportation, find the probability that the commuter had a commute of 60 6060 or more minu

AlladinOne [14]

<u>Complete Question</u>

The two-way table below gives the thousands of commuters in Massachusetts in 2015 by transportation method and one-way length of commute.

$\left|\begin{array}{c|c|c|c|c|c|c}$Transport Mode/Minutes&$Less than 15&15-29&30-44& 45-59&$60 or more &$Total\\---&---&---&---&---&---&---\\$Private vehicle & 636&908&590&257&256&2647\\$Public Transportation&9&54&96&62&108&329 \\$Other&115&70&23&7&7&222\\---&---&---&---&---&---&---\\$Total&760&1032&709&326&371 &3198 \end{array}\right|$

Answer:

$\dfrac{108}{329}$

Step-by-step explanation:

From the table above

Total Number of commuters who used public transportation=329

Number of commuters who spent 60 or more minutes on public transportation=108

Therefore:

Given that a commuter used public transportation, the probability that the commuter had a commute of 60 or more minutes:

P ( 60 + minutes ∣ public transportation ) = $\dfrac{108}{329}$
