Answer:
Step-by-step explanation:
<u>Total number of integers from 300 through 780, inclusive:</u>
<u>Number of integers with at least one of digit 1:</u>
- Hundreds - 0,
- Tens - 5*10 = 50 (31th, 41th, 51th, 61th, 71th)
- Units - 4*9 + 7 = 43 (300 till 699 and 700 till 780)
- So in total 50 + 43 = 93
<u>The probability is:</u>
- P = favorable outcomes/total outcomes = 93/481

Step-by-step explanation:
x= how many members are in the group
x= 100/x
x= 100/(x-5)
x(x-5)=100
x^2-5x=100
x^2-5x-100=0
and then use the quadratic formula (i can't type it srry)
