Answer:
Step-by-step explanation:
In order to isolate D, multiply by T on both sides.
The probability of each is the fraction of that item (or group of items) to the total. They just tried to trick you by listing Science with subcategories of biology and chemistry to see if you would add them twice and get the wrong total. Total rooms is M+S+E=5+10+10=25
S=10/25
B=8/25
M=5/25
E=10/25
C=2/25
For the "or" questions you just add them. P(MorE) = P(M) = P(E).
<span>For S and not C that's just B.
I hope my answer has come to your help. God bless and have a nice day ahead!
