Step-by-step explanation:

We can use normal aproximation, assuming that the random variables are a lot of that means the sample size is large.

$P(x>105) = P(z>\frac{105-100}{1})=P(z>5)$

Using the normal distribution table,

P(z>5) = 0.00005

Hence, we can conclude that the probability that the stock’s price will exceed 105 after 10 days is very small.

Hope this helps!
