If Jenny can read 7 books in 8 days, exactly how many days would it take her to read 20 books?
muminat

Answer:

<h2><em><u>23</u></em><em><u> </u></em><em><u>days</u></em></h2>

Step-by-step explanation:

<em><u>Given</u></em><em><u>,</u></em>

No. of days taken by Jenny to read 7 books

= 8

<em><u>So</u></em><em><u>,</u></em>

No. of days taken by her to read 1 book

=  \frac{8}{7}

<em><u>Therefore</u></em><em><u>,</u></em>

No. of days taken by her to read 20 books

=  \frac{8}{7} × 20

  • <em>[</em><em>On</em><em> </em><em>Simplification</em><em>]</em>

=  \frac{160}{7}

  • <em>[</em><em>On</em><em> </em><em>dividing</em><em>]</em>

= 22.85.....

  • <em>[</em><em>On</em><em> </em><em>approximating</em><em>]</em>

= 23 days (approx. )

<em><u>Hence</u></em><em><u>,</u></em>

<em><u>Jenny</u></em><em><u> </u></em><em><u>will</u></em><em><u> </u></em><em><u>take</u></em><em><u> </u></em><em><u>23</u></em><em><u> </u></em><em><u>days</u></em><em><u> </u></em><em><u>to</u></em><em><u> </u></em><em><u>read</u></em><em><u> </u></em><em><u>20</u></em><em><u> </u></em><em><u>books</u></em><em><u> </u></em><em><u>(</u></em><em><u>Ans</u></em><em><u>)</u></em>

natta225 [31]

Answer:

The probability that there will be repair exactly 3 toaster is 0.0574.

Step-by-step explanation:

Binomial Distribution:

A discrete random variable X having the set {0,1,2,3......,n} as the spectrum, is said have a binomial distribution with parameter n= number of trials and p=probability of number of success on an individual trial, if the p.m.f (probability mass function) of X given by,

P(X=x)=C(n,x)p^x(1-p)^{n-x}    x=0,1,2,......,n

               =0                                   elsewhere

where 0<p<1 and n is a positive integer.

Total number of toaster in cartons(n) = 10.

Probability of number of success on an individual trial p= 10% = 0.10

\therefore P(X=3)= C(10,3)(0.10)^3(1-0.10)^{10-3}

                    =\frac{10!}{3!(10-3)!}(0.10)^3)(0.90)^7

                    =0.0574

The probability that there will be repair exactly 3 toaster is 0.0574.
