Answer:
The union of two event
Step-by-step explanation:
Addition law of probability define that probability of two event is total sum of probability of any event subtract the probability of both events
There are two rules in addition law:
Addition law 1 - when both event are mutually exclusive, then probability of either event is the sum of each event probability.
P( A or B) = P(A) +P(B)
Addition law 2 - when both events are non mutually exclusive then there in addition to the individual probability there is some overlap .
P( A or B) = P(A) +P(B) - P(A and B)
Answer:
f(x)=-3/2x+1
Step-by-step explanation:
y=mx+b
m=slope
b=y intercept
y=f(x)
Answer:
1.4000
2.5.551
3.6.8
4.10.00
5.4
Step-by-step explanation:
1 4066 as an example start from the end a 5 or more it turns to a zero and the one next to it
so in this case we now have 4100 but since it isn't 5 or more we make it a zero and move on so now we have 4000
sorry if I am wrong I am also an idiot so hopefully this helps for the future :)
Gemma was hiking for 2 1/2 a hour for 3 hours so u have to multiply 2.5 by 3 and that gonna equal 7.5 so u leave that alone and come back to it later so u get 11 3/8 minus 7.5 and it gonna equal 3 7/8 and I hope that helped you
