Answer:
(C) The probability of buying bread and cheese is 0.12
Step-by-step explanation:
P(Event A) = 0.6
P(Event B) = 0.2
If Event A and Event B are independent,
Then P(Event A and Event B) = 0.6 x 0.2 = 0.12
Answer:
area =12
Step-by-step explanation: you don't need to use all 4 numbers just used the base which is 8 then times it with 3 which gives you 24 then divided it by 2 which gives you 12.
A straight line adds up to 180
So the line opposite of 137 should add up to 180
This gives us the equation 137+x=180 then x=43
The triangle also adds up to 180 degrees
So 102+43+x=180
The equation can be simplified to 145+x=180 therefore x=35
So x+?=180 because it is a straight line.
We can substitute x in making the equation 35+?=180
Now we want to solve for the ? so we'll subtract 35 from each side
This leaves us with the equation ?=145
So we now know that the ?=145
