Answer: Our required probability is 0.55.
Step-by-step explanation:
Since we have given that
Probability that chance of winning the hotel bid = 40%
Probability that no chance of winning the hotel bid = 100-40=60%
Probability that chance of winning the office building bid = 25%
Probability that no chance of winning the office building bid = 100-25 = 75%
So, Probability that the company will win at least one contract is given by

Hence, our required probability is 0.55.
The diameter of the sphere is 60 mm which means its radius is 30mm. <span>The radius of a sphere is increasing at a rate of 5 mm/s.
The formula for the radius when the time is x second would be:
</span>r(t)<span>= 30+ 5x
dr/dt= 5
The speed of </span><span>volume increase </span><span>of the sphere volume would be derived from sphere volume:
</span>V(r)=4/3* pi * r^3<span>
dV/dt= 4/3 * pi * 3r^2 * (dr/dt) =4/3* pi * 3(30)^2 * 5 = 18000 pi= 56571 mm^3/s</span>
