Answer 1

Since we know that the customer ordered a hot drink, let's find the total amount of customers that ordered a hot drink:

`\text{total hot}=5+48+22=75`

Now, to find the probability of a customer ordering a large, given that the customer ordered a hot drink, we just need to divide the number of clients that ordered a large hot drink by the number of clients that ordered a hot drink:

`P(\text{large}|\text{hot)}=\frac{\text{large hot}}{\text{total hot}}=(22)/(75)=0.2933=29.33\text{\%}`

Rounding to the nearest percent, we have a probability of 29%.
