Step-by-step explanation:
Since density is the ratio of mass to (in this case) area, we can find the mass of the triangular region by computing the double integral of the density function over :
The boundary of is determined by a set of lines in the plane. One way to describe the region is by the set of points,
So the mass is
Answer:
0.397
Step-by-step explanation:
In the experiment, if the coin is flipped 4 times, the outcomes in which there is a single heads out of the 4 flips are:
HTTT,THTT,TTHT and TTTH
The probability of flipping a head, P(Head)=0.18
Therefore: The probability of flipping a tail, P(Tail)=1-0.18=0.82
We can then calculate the probability that there is a single heads out of the 4 flips
=P(HTTT)+P(THTT)+P(TTHT)+P(TTTH)
=(0.18 X 0.82 X 0.82 X 0.82) + (0.82 X 0.18 X 0.82 X 0.82) + (0.82 X 0.82 X 0.18 X 0.82 )+ (0.82 X 0.82 X 0.82 X 0.18)
