Answer:
mutually exclusive
Step-by-step explanation:
The formula of interest is ...
P(A or B) = P(A) + P(B) - P(A and B)
Filling in the given values, we have ...
9/10 = 2/5 + 1/2 - P(A and B)
Solving for P(A and B), we get ...
P(A and B) = 2/5 +1/2 -9/10 = 4/10 +5/10 -9/10
P(A and B) = 0
__
Events are mutually exclusive when <em>they can never happen at the same time</em>. That is, P(A and B) = 0.
The events A and B are mutually exclusive.

Answer:
150 tickets
Step-by-step explanation:
Given: Tickets sold at four different gates
Gate B sold 26 % tickets
Tickets sold at Gate B = 39
Let take x as total number of tickets sold at all four gates.
Now, using the value of gate B to find total number of tickets
∴ 
⇒ 
Next, cross multiply both side
⇒ 
∴ Total tickets sold at all the four gates is 150
You would count the amount of squares going up then count the squares going horizontal, so then it would be 5/3 hole this helps:)
