Asap pl hasan has a bag of 25 counters. 15 of the counters are black. 10 of the counters are white. hasan works out that the probability of picking two counters is (2/5)²=4/25 what assumption has hassan made for this probability to be true?

Given,

There are a total of 25 counters

15 of the counters are black.

10 of the counters are white

Hasan calculates the probability of picking two counters to be (2/5)^2 = 4/25

For this probability to be true, Hasan has made the assumption that he would pick two white counters consecutively.

Probability of picking two white counters consecutively

= (10/25) * (10/25)

= (10/25)^2

= (2/5)^2

= 4/25

use an equation of ratios to determine the amount of gas needed to fill the tank.

    0.2             0.8

  =    

288.75             x

                                                              231 gal

so, 0.2x = (0.8)(288.75 gal), and x = = 1155 gal.

                                                                0.2

it would take 1155 gal. to fill the tank.

the cost would be

1155 gal         $3

* = $3465   (answer)

      1           1 gal

hope this you

7! = 7×6×5×4×3×2

3! = 3× 2

as 7! is multiple of 3! because 7! contains 3! that is 3× 2 as factor

so 7! /(3! ) = 7× 6× 5× 4

= 42 × 20

= 840

its b) 840✌✌✌
