Find the probability of selecting none of the correct six integers in a lottery, where the order in which these integers are selected does not matter, from the positive integers not exceeding the given integers.
a. 40
b. 48
c. 56
d. 64
Answer:
a. 0.35
b. 0.43
c. 0.49
d. 0.54
Explanation:
(a)
The objective is to find the probability of selecting none of the correct six integers from the positive integers not exceeding 40.
Let s be the sample space of all integer not exceeding 40.
The total number of ways to select 6 numbers from 40 is
.
Let E be the event of selecting none of the correct six integers.
The total number of ways to select the 6 incorrect numbers from 34 numbers is:
![|E| = C(34,6)](https://img.qammunity.org/2021/formulas/mathematics/college/4pwvnoijvjus9algpp4cao2lwaib6uj7ep.png)
Thus, the probability of selecting none of the correct six integers, when the order in which they are selected does rot matter is
![P(E) = (|E|)/(|S|)](https://img.qammunity.org/2021/formulas/mathematics/college/pcdkv0vflx0gzpcqawcz6mtkbimmnini5w.png)
![= (C(34, 6))/(C(40, 6))\\\\= (1344904)/(3838380)\\\\=0.35](https://img.qammunity.org/2021/formulas/mathematics/college/i1puqlygt7sajiyd9xzgujm3162cjtl15b.png)
Therefore, the probability is 0.35
