Answer:

9/10

30%

Explanation:

Only in trial number 4, there is just one correct answer. In all other 9 trials at least 2 answers were correct. So the probability is 9 out of 10 trials give a winning outcome, in short, 9/10.

Giving birth to three males first, is true in 3 out of 10 trials. You can count the total numbers of Y's in the last column.

So 3/10 which is 0.3 which is the same as 30%.
