81 - 35+30 (55) = 26 therefore 26cm is ur final answer
Answer:
the last one 1/6
Step-by-step explanation:
1/2 x 1/3 = 1/6
The probability of getting number 5 rolled 6 times is 1/500.
Here, Total rolls = 10 times
Probability of getting 5 on one roll = 1/6
Probability of not getting 5 on one roll = 5/6
Total Probability for getting 5 6 times after rolled 10 times
= ¹⁰C₆(1/6)⁶(5/6)⁴
= 210 X (0.167)⁶(0.833)⁴
= 0.002
= 1 / 500
Thus, the probability of getting number 5 rolled 6 times is 1/500.

Probability is quite simple. In this case, you just need to find the total number of balls (28) and the total number of black balls (20) Now, create a ratio (20/28) Next, simplify it down to 5/7, and that is your answer. I hope that helps! :)
