The answer is 9 because 5*(-3)+8+9-(-7)=9
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

To solve this question we have to apply trigonometric ratios
sin31=UT/TV
TV=UT/sin31
=7.76
=7.8
Hope this helps.
