Should be S(1, -9) because you are rotating it 90 degrees which is 1/4 of 360 degrees.
Dividing b 8 is same as mutiiplying by 1/8
144=80+64
1/8(80+64)=1/8(80)+1/8(64)=10+8=18
Given:
Number of spheres = 2
Number of prisms = 3
Number of pyramids = 5
To find:
The probability that a pyramid will be selected.
Solution:
We have,
Favorable outcomes = Number of pyramids
= 5
Total outcomes = Total number of figures
=
=
Now, the required probability is:
Therefore, the probability that a pyramid will be selected is 0.5.
