All you need to do is multiply the fractions:
1/2*1/8
Answer: 1/16
So, each friend gets 1/16 of the cake.
It is important to note that all the information's required are already given in the question
Probability that a day will be hot = 0.15 + 0.10
= 0.25
Probability that a day will be sunny = 0.15 + 0.30 + 0.10
= 0.55
Adding the above two probabilities, we get = 0.25 + 0.55
= 0.80
Now
Probability that a day will be both hot and sunny = 0.15
So
Probability that a day was hot or sunny = 0.80 - 0.15
= 0.65
I hope the procedure is clear enough for you to understand.
Answer:
The measure of x = 45 degrees
20/25*2(5-10)=20/25*10-20 later calculate the numbers
