Answer:
0.0549
0.7617
0.2383
Step-by-step explanation:
Given that:
Probability that incoming email is spam ;
P(spam) = 0.38
If three emails are in my inbox, what is the probability that:
A. All three messages are spam.
P(1st message being spam) * p(second message being spam) * p(3rd message being spam)
= (0.38) * (0.38) * (0.38)
= 0.054872
= 0.0549
B. At least one of the three messages are spam.
1 - p(none of the 3 messages are spam)
P(none of the 3 messages are spam)
P(not spam) = 1 - p(spam) = 1 - 0.38 = 0.62
1 - [P(not spam) * p(not spam) * p(not spam)]
1 - (0.62 * 0.62 * 0.62)
= 1 - 0.238328
= 0.761672
= 0.7617
C. None of the three messages are spam.
P(not spam) = 1 - p(spam) = 1 - 0.38 = 0.62
P(not spam) * p(not spam) * p(not spam)
(0.62 * 0.62 * 0.62)
= 0.238328
= 0.2383
2x + 2x + 124 + 124 = 360
4x + 248 = 360
2x = 360 - 248 = 112
x = 112/2 = 56
The answer is 10 2/3 because 3/4 equals .75. 8 divided by .75 equals 10 2/3
It'll be 3/4 lbs I'm pretty sure...
Answer:
Slope is -2/7
Step-by-step explanation:
Slope formula is y₂-y₁/x₂-x₁
So...
(x₁,y₁) and (x₂,x₂) →(2,2) and (-5,4)
4-2= 2
-5-2= -7
2/-7
