Answer:
The probability of waking up early at least one day is 1.2
Step-by-step explanation:
We are given the tree diagram
We are supposed to find the probability of waking up early at least one day
So, we are supposed to find the probability of waking up early for 1 and more than 1 day
By studying the tree diagram
So the probability of waking up early for 1 and more than 1 day =[tex]\frac{2}{5}+\frac{2}{5}+\frac{2}{5}[/tex]
The probability of waking up early at least 1 day = [tex]\frac{2}{5}+\frac{2}{5}+\frac{2}{5}=1.2[/tex]
Hence the probability of waking up early at least one day is 1.2
