Answer:
d) The binomial distribution with n = 4 and p = 0.5
Step-by-step explanation:
They re 10 cards consisting of 5 red cards and 5 black cards which are shuffled thoroughly and choosing at random. After choosing the cards are replaced back.
The probability of choosing a red card = number of red cards / total number of cards = 5 / 10 = 0.5
The probability of choosing a black card = number of black cards / total number of cards = 5 / 10 = 0.5
Since after choosing, the cards are replaced back and shuffled making the next draw independent of the previous draw repeated four times. This is a binomial distribution with n = 4 and p = 0.5
It should just be 3 15/16 because you can’t really simplify 15/16 because it’ll just give you decimals. For example; 15/3 is 5 but 16/3 is 5.333.... and 15/5 is 3 and 16/5 is 3.2, and 15/2 is 7.5 and that won’t work because it turns into a decimal.
