A certain insecticide kills 60% of all insects in laboratory experiments. A sample of 12 insects is exposed to the insecticide i
Vilka [71]

Answer:

The probability that exactly 10 insects will die

                     P( X = 10 ) = 0.06385        

Step-by-step explanation:

<u><em>Step(i):-</em></u>

Given a certain insecticide kills 60% of all insects in laboratory experiments

Given proportion  p = 0.60

                           q = 1 - 0.60 = 0.40

Given sample size 'n' = 12

<u><em>Step(ii):</em></u>-

Let "X' be the random variable of binomial distribution

                              P(X=r) = n_{C_{r} } p^{r} q^{n-r}

The probability that exactly 10 insects will die

                              P(X=10) = 12_{C_{10} } (0.60)^{10} (0.40)^{12-10}

                           

                          n_{C_{r} } = \frac{n!}{(n-r)!r!} = \frac{12!}{(12-10)!10!} = 66

                          P(X=10) = 66 X (0.60)^{10} (0.40)^{2} = 0.06385

<u><em>Final answer:</em></u>-

The probability that exactly 10 insects will die

                     P( X = 10 ) = 0.06385

Willy and Billy each have a rock collection. • The number of rocks in Willy’s collection can be represented by x. • The number o
andriy [413]
There are 30 rocks in Willy's collection.

Since the number of rocks in Willy's collection is x, the number in Billy's collection is (2 2/3)x or 8/3x.

x+(2 2/3)x = 110
(3 2/3)x=110
11/3x = 110

Dividing both sides by 11/3,
(11/3x)÷11/3 = 110÷11/3
x = 110÷11/3 = 110/1 ÷ 11/3 = 110/1 × 3/11 = 330/11 = 30
