Q80.A biased die is marked with numbers 2, 4, 8, 16, 32, 32 on its faces and the probability of getting a face with 1 mark ๐ is ๐. If the die is thrown thrice, then the probability, that the sum of the numbers obtained is 48, is (1) 7 (2) 7 211 212 3 13 (3) (4) 210 212
What This Question Tests
This question tests the ability to list all possible combinations of outcomes from three throws of a biased die that sum to 48, and then calculate their probabilities using the given probability distribution.
Concepts Tested
