Hello guys, I need help with the following problems:
- select a positive 2 digit number less than 50. P(factor of 4)
- select a positive 2 digit number greater than 59. P(factor of 7)
- select a factor of 72. P(factor will be odd)
- toss a coin 3 times. P(not getting 2 tails and 1 head)
- toss 3 coins. P(getting 1 tail and 2 heads)
- a coin is tossed 7 times. 3 times it comes out heads and 4 times it comes out tails. What is the probability that you will get tails on the next loss?
