Answer:
29/61
Step-by-step explanation:
okay, first imma simplify the question a little bit.
122 students; 46 chose football; 18 chose tennis; 28girls + xboys chose running.
okay now let's find the number of students who chose running
122 - 46 - 18 = 58
now, I'll find the probability
P(Running) = 58/122 = 29/61

Answer:
The probability that the bulb will last more than 1,200 hours is 0.3012
Step-by-step explanation:
Let the random variable <em>X</em> = life of a light bulb .
The random variable
The probability distribution function of exponential distribution is:
The mean of the distribution is, Mean = 1000 hours.
The value of λ is:
Compute the probability that the bulb will last more than 1,200 hours as follows:
Thus, the probability that the bulb will last more than 1,200 hours is 0.3012.
We use long division to divide
There is no x term in x^2 -1 so we put 0x
x + 1
----------------------------
x^2+0x-1 x^3+ x^2 + x+ 2
x^3+0x^2-x
-----------------------------(subtract the bottom from top)
x^2 +2x + 2
x^2 +0x - 1
--------------------------------(subtract the bottom from top)
2x + 3
-----------------------------------------
Quotient : x+1
Remainder : 2x+3
