a six sides number cube is rolled 25 timess and lands on 2 five times and on 6 three times what is the probibility of rolling a 2
can you not do the 25 and do 2 five times by 6 three times. the probability of that not 25
The probability of rolling a 2 on a six-sided number cube is 1/6.
Since the number cube is rolled 25 times and lands on 2 five times, the probability of rolling a 2 in 25 rolls is 5/25 = 1/5.
Therefore, the probability of rolling a 2 on a six-sided number cube is 1/6, or approximately 16.67%.
Apologies for the confusion.
If the number cube is rolled 25 times and lands on 2 five times and on 6 three times, the remaining rolls must land on the other numbers 1, 3, 4, or 5.
The probability of rolling a 2 on a six-sided number cube is 1/6.
Since the cube is rolled 25 times and lands on 2 five times, the number of additional rolls should be 20 (25-5=20).
The probability of not rolling a 2 in one roll is 5/6.
Therefore, the probability of not rolling a 2 in 20 rolls is (5/6)^20.
So, the probability of rolling a 2 in 25 rolls when it lands on a 2 five times and on 6 three times is calculated as:
1/6 (probability of 2) * (5/6)^20 (probability of not 2 in 20 rolls) ≈ 0.0203 or 2.03%.
