Answer:
Option D. 3/4
Explanation:
From the question given above, we obtained the following information:
Block with letter = 3
Block with symbol = 1
Total = 4
Thus,
Sample space (S) = 4
Event of block with letter (nBl) = 3
Event of block with symbol (nBs) = 1
Finally, we shall obtain the probability of picking a block with letter as follow:
Sample space (S) = 4
Event of block with letter (nBl) = 3
Probability of picking a block with letter, P(Bl) =?
P(Bl) = nBl/nS
P(Bl) = 3/4
Therefore, the probability of picking a block with letter is 3/4.
