Question

10 POINTS QUICK TIMED TEsT
The relative frequency table shows the results of a survey in which parents were asked how much time their children spend playing outside and how much time they spend using electronics.



Given that a child spends at least 1 hour per day outside, what is the probability, rounded to the nearest hundredth if necessary, that the child spends less than 1 hour per day on electronics?

0.22
0.25
0.70
0.88

Answer 1

Answer:

0.88

Step-by-step explanation:

We would consider the first case second column....

So 14/16 will be the probability that comes out be approximately 0.88.

Pls tell what the right answer is ...

Nice question btw

Answer 2

The required probability is 0.88.

Total number of children spending at least an hour a day outside = 16  (Given)

Total number of children spending less than an hour a day on electronics = 14 (Given)

Time that a child will spend outside = 1 hour  (Given)

Let the number of children spend at least 1 hour/day outside = x

Therefore,

P (x) = Children spending day outside/children spending time on electronics

P (x) = 14/16.

= 87.5%

Rounding off the percentage it will be 88%

Thus, the nearest 100th will be 0.88.
