Step-by-step explanation:
For all y values, just look along the y-axis. The same applies to the x-axis.
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.
(70+71+72+x)/4 ≥ 73
(213+x)/4 ≥ 73
213+x ≥ 73*4
213+x ≥ 292
-213 -213
x ≥79
Check:
(70+71+72+80)/4
292/4
73.25
Your Answer:
x ≥ 79
Answer:
x=4
