Answer: 15/16
Step-by-step explanation:
There will be 16 outcomes for 4 coins=2^4
Probability of only head is : P(C)=1/16
P(C) + P(C') = 1
P(C') = 1 - P(C)
P(C') = 1 - 1/16
Take the l.c.m
P(C') = (16-1) / 16
P(C') = 15/16
So the probability of getting at least 1 tail is 15/16
17/100, I believe
(the decimal would be 0.17)
The rule of the transformation is
(x,y)->(-y,x)
which corresponds to a 90 counterclockwise rotation about the origin,
which in turn corresponds to a 270 clockwise rotation about the origin.
Note that all rotations preserve lengths and angles, hence the image and preimage are congruent.
A is 4/9 B is 4/15 C is 8/5 D is 3/10
