Answer:

P(3) = 0.0244

P(3) = 2.44%

the probability that all three selected have driven while under the influence of alcohol is 2.44% or 0.0244

Step-by-step explanation:

Given;

The probability that they have driven while under the influence of alcohol is;

P = 29% = 0.29

the probability that all three selected have driven while under the influence of alcohol is;

P(3) = P × P × P

P(3) = 0.29 × 0.29 × 0.29

P(3) = 0.024389

P(3) = 0.0244

P(3) = 2.44%

the probability that all three selected have driven while under the influence of alcohol is 2.44% or 0.0244

Mr mehra spends 30% of his income in food 10% on charity 25% and is left with 15750 what is his salary? find his savings
nalin [4]

Answer:

Mr mehra's salary is 26250

Step-by-step explanation:

suppose,

Mr mehra's salary is x

so,

He spends in food = 30% of x

                               =(30/100) . x      [x%=x/100]

                                = 30x/100

                                =3x/10

He spends in charity =10% of x

                                    =10x/100

                                    =x/10

Money left = 15750

so,

x = 3x/10 + x/10 +  15750

⇒x - 3x/10 - x/10 = 15750

⇒(10x-3x-x) /10 = 15750

⇒6x/10 = 15750

⇒6x=157500

⇒x = 157500/6

⇒x = 26250

∴Mr mehra's salary is 26250
