Johnny wants to buy a lottery ticket, so he decides on the ones that give him a 1 in 3 chance of winning! If Johnny buys 15 lottery tickets, how many times would you expect him to win?

5 or less chances.

Step-by-step explanation:

well because if he buys 15, 1 in 3 chance tickets, the highest amount of times he would win would  be 5 because 15 is the chances of winning multiplied by the tickets he could win.

hope it

step-by-step explanation:

x^(1/6) · x^(1/6) · x^(1/6)   ·x^(1/6) = x^(4/6)   since we add the exponents

4/6 can be simplified to 2/3

the simplified form is x^(2/3)

e^-kt = n/n0 = 0.79  

-kt = ln 0.79  

t = - ln 0.79/0.0001  

= 2357 years
