Answer:
Your answer would be the first option.
A right angle is 90 degrees
An obtuse angle is more than 90 degrees and that angle is more that 90 degrees
Answer c: 2 and 3
Of course Q is on plane PQR. If S is as well, then QS is as well.
To simplify this expression would be 4x-3
To get the required value of the missing probability to
make the series complete is to deduct all the probability given to 1 because we
know that the discrete probability distribution must be equal to 1. So doing
what I have said, this will be:
P(4) = 1 - P(3) - P(5) - P(6)
= 1 – 0.3 – 0.18 – 0.21
<span>= 0.31 is the answer.</span>
