Q # 4 please help to solve

Answer 1

The second choice - 3.1%

All you have to do is multiply the probability by itself five times to get the total probability for the next five days.

1/2*1/2*1/2*1/2*1/2 
= 1/2! 
= 1/32 
= 0.0313 
= 3.13% 

3.13 rounded off to the nearest tenth is 3.1%
There is 3.1% probability that Shania will arrive at school on time for the next five days.
