How does the binomial distribution do this? Basically, a two part process is involved. First, we have to determine the probability of one possible way the event can occur, and then determine the number of different ways the event can occur. That is, P(Event) = (Number of ways event can occur) * P(One occurrence).

• b) P (more than 1) = (PX>1)=P(2+P3+P4 =0.100+0.040+0.010 =0.150 “More than 1” excludes 1, and we go higher. • c) P (at most 2) = (PX≤2)=P(0+P1+P2 =0.650+0.200+0.100 =0.950 “At most 2” includes 2, and we go lower. It may be easier to subtract the complementary probability, P(3)+P(4), from 1: P(X≤2)=1−⎡⎣P(3)+P(4)⎤⎦

Answer: P( x >2) = [P(x=4) +P(x =5) + P(x =10)] = (.3 +.3 +.2) =.8. μ = Σxp(x) = 2(.2) + 4(.3) + 5(.3) + 10(.2) = 5.1. σ2 = Σx2p(x) μ 2 = 4(.2) + 16(.3) + 25(.3) + 100(.2) (5.1) 2 = 33.1 – 26.01 =7.09. σ = 2.66. P(X ≤ 4) = P(x=2) +P(x =4) = .5. μ σ = 5.1 – 2.66 = 2.44. μ + σ = 5.1 + 2.66 = 7.76.

For example, if we toss a biased coin. We may want to say that P{heads} = p where p is not necessarily equal to 1/2. By necessity, P{tails} =1p. Example 5.3. Toss a coin 4 times. P{fewer than 3 heads} =1P{at least 3 heads} =1 5 16 = 11 16. 2. The Difference Rule. Write B \A to denote the outcomes that are in B but not in A. If A ⇢ B, then P(B ...

2. Twice a number p is fewer than 7. 3. A number w minus 3 is less than or equal to 10. 4. A number z divided by 2 is at least 6. A solution of an inequality is a value that makes the inequality true. An inequality can have more than one solution. The set of all solutions of an inequality is called the solution set.
