Answer 2

Step-by-step explanation:

If a coin is tossed six times there will be 26 = 64 possibility outcome. A denotes the event that 4 or more heads comes. . The possibility that atleast 4 heads comes = probability exactly 4 heads + probability of exactly 5 heads + probability of exactly 6 heads comes. Probability of 4 heads comes = First tail can take in any of the 6 positions and the 2 tail can take exactly. any of the 5 positions. Therefore, there are 6*5 = 30 possible outcome. Probability exactly 5 heads counts = the tail can take any of the 6 position therefore possibility outcome are 6. Probability exactly 6 heads comes there are only 1 possible outcome the probability of obtaining 4 or more heads are 30+6+1/ 26. = 37/64.
