If they start at 4 on the y-axis, they can go down to 1 or go up to 7. Then we just add the -3 to the x axis.
Answer:
X : ___ 0 ____ 1 _____ 2 ______ 3
P(X) : _ 6/15 __ 5/15__ 3/15 ____ 1/15
Step-by-step explanation:
From the data, to produce a probability distribution for the data :
X : number of times blood is drawn ;
P(x) : probability that blood is drawn at X times
Hence, the probability distribution table for the data Given goes thus :
X : ___ 0 ____ 1 _____ 2 ______ 3
P(X) : _ 6/15 __ 5/15__ 3/15 ____ 1/15
Probability that blood is drawn 0 times = 6/15
Probability that blood is drawn 1 time = 5/15
Probability that blood is drawn 2 times = 3/15
Probability that blood is drawn 3 times = 1/15
(6/15 + 5/15 + 3/15 + 1/15) = 1
There were 4 musicians in the bad last month
The missing angles are the one with labels 1, 2, 3, 4.
180 = 43 + 69 + X
180 = 112 + X
X = 68 (1)
180 = 112 + 41 + Y
180 = 153 + Y
Y = 27 (2)
180 = 44 + 66 + Z
180 = 110 + Z
Z = 70 (3)
180 = 109 + 29 + Z
180 = 138 + Z
Z = 42 (4)
