Question 1119136
<br>
Obviously we can't use the table in the appendix of your text to answer your question....!<br>
Since the problem is about binomial probability, n is probably the number of trials (10), x is probably the number of favorable outcomes (heads; 4), and p is the probability of getting heads on each flip (presumably 1/2, since the coins should be fair coins if the statement of the problem doesn't say otherwise.)<br>
To find the probability of getting 4 heads on 10 flips of a fair coin, without using your table, the denominator of the probability fraction is 2^10=1024, because there are two equally likely outcomes on each flip; the numerator is the number of ways 4 of the 10 flips can be heads, which is "10 choose 4", 10C4 = 210.<br>
The probability is then 210/1024 = 105/512.
