Answer:
0.7
Step-by-step explanation:
Probability of defective = 0.7
P(non-defective) = 1 - 0.7 = 0.3
Let X be the trial at which we get the first non-defective
Then X follows a geometric distribution.
X ~ Geo (0.3)
What has happened already will not affect the probability.
P(atleast 2 more) = P(X > 1)
= 1 - P(X = 1)
= 1 - (0.3)
= 0.7
Answer:
It will measure 75 millimetres on the plan.
Step-by-step explanation:
Given:
Scale on the plan = 1:100
Length of the fence = 7,500 mm
To find:
how many millimetres will it measure on the plan
Solution:
As the ratio on the plan is 1: 100, the for 7500 the ratio will
x : 7500
Now by cross multiplication we get
x = 75
Answer:
A) 27
B) 1/9
C) 1/9
Step-by-step explanation:
A) 3×3×3 = 27 outcomes
B) (3×2)/27 = 1/9
C) first one is a purple, probability of next 2 being orange is:
1/3 × 1/3 = 1/9
Answer: C. decreased . . . increase.
As technology is advancing it requires less time and effort to do almost anything. So for tranportation as well i think it will take less time to do it. Thus logically people would want to trade more because the transport goods take less time. I guess?
