Answer:
The probability of failure of both the bulbs is 0.4323.
Step-by-step explanation:
For an exponential distribution the distribution is given by
The value of λ is related to the mean μ as λ=1/μ,
Let us denote the 2 bulbs by X and Y thus the probability distribution of the 2 bulbs is as under
Similarly for the bulb Y the distribution function is given by
Thus the probability for both the bulbs to fail within 1500 hours is
Answer:
Step-by-step explanation:
Neither...there is no common difference nor a cmon ratio do neither
3 tests at 75% each = 3 x 75 = 225 total points
First two tests = 79 + 84 = 163
Third test needs to be at least: 225 - 163 = 62%
So any score less than 62 would get you into trouble.
