Answer:

Kyle

Step-by-step explanation:

Kyle:

Kyle’s parents told him that for every 5 hours of homework or reading he completes, he will be able to play 3 hours of video games.

Victor:

Victor’s parents told their son that he can play 30 minutes for every hour of homework or reading time he completed. If Victor spends 5 hours doing homework or reading, then he could play

$30\cdot 5=150$ minutes

that is

$120+30=2$ hours $30$ minutes (less than 3 hours).

Hence, if both boys spend the same amount of time on homework and reading this week, then Kyle will have more time to play video games.

The probability that someone owns an iPhone is 62%. The probability that someone owns an Apple watch is 15%. The probability som

Dmitry [639]

ANSWER

The probability that someone owns an iPhone or an Apple watch is

$P(I \cup \: A) = 69\%$

or

$P(I \cup \: A) = 0.69$

EXPLANATION

We were given that, the probability that someone owns an iPhone is

$P(I)=62\%$

and the probability that someone owns Apple watch is

$P(A)=15\%$

and the probability that someone owns both is

$P(I \cap \: A) = 8\%$
Since the intersection is not zero, it means the two events are not mutually exclusive.

The probability that someone owns an iPhone or Apple phone is

$P(I \cup \: A) = P(I) + P(A) - P(I \cap \: A)$

We substitute the values to get,

$P(I \cup \: A) = 62\% + 15\% - 8\%$

$P(I \cup \: A) = 69\%$
