We find the slope through the formula y2-y1/x2-x1
so when we plug in the values of our two points, we get
2-(-1)/(0-(-1))
this gets us 3/1
Which gives us the slope m=3
Assuming that 10% is the probability of a switch being defective (since left-handedness has nothing to do with the problem):
For a binomial distribution, probability(r out of n) = (nCr) (p)^r (q)^(1-r)
p = 10% = 0.1, q = 1 - p = 0.9
r = 2 switches, n = total of 12 switches
probability = (12C2) (0.1)^2 (0.9)^(12-2)
probability = 66(0.1)^2 (0.9)^10
probability = 0.23

Answer:
$24
Step-by-step explanation:
Since you know 5 tickets equal to $60, and you want to find the cost of one ticket, you would divide 60 by 5. 60/5=12. So each ticket costs 12 dollars. But you want to find the cost of two. So multiply $12 by two to get $24 dollars per two tickets.
