Now, the number bacteria in the food in h hours is given by:-
So, The number bacteria in the food in h hours is given by:
You would be multiplying pi (3.14) by the number 5
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.
