(a) The probability of getting a head is the ratio of the number of times a head was obtained to the total number of tosses. In this case, a head was obtained 245 times out of 500 tosses. Therefore, the probability of getting a head is:
245/500 = 0.49
(b) The probability of getting a tail is the complement of the probability of getting a head, since there are only two possible outcomes. Therefore, the probability of getting a tail is:

Step-by-step explanation:
(a) The probability of getting a head is the ratio of the number of times a head was obtained to the total number of tosses. In this case, a head was obtained 245 times out of 500 tosses. Therefore, the probability of getting a head is:
245/500 = 0.49
(b) The probability of getting a tail is the complement of the probability of getting a head, since there are only two possible outcomes. Therefore, the probability of getting a tail is:
1 - 0.49 = 0.51
So, the probability of getting a tail is 0.51.
Verified answer
Answer:
(a) Probability of getting a head = Number of heads / Total number of tosses
= 245 / 500
= 0.49 or 49%
(b) Probability of getting a tail = Number of tails / Total number of tosses
= 255 / 500
= 0.51 or 51%
