Answer:
Step-by-step explanation:
Since, the initial number of hot dogs = 4
According to the question,
The number of hot dogs is increasing by 110% of that of previous day,
Thus, the number of hot dog in first day = 4
Second day = 110 % of 4 = 4.4
Third day = 110% of 4.4 = 4.84
Fourth day = 110% of 4.84 = 5.324
So on.......
Thus, we get a GP,
4, 4.4, 4.84, 5.324 ..........................
That having common ratio, d = 1.1
And, first term, a = 4
Since, the nth term of the GP,
Hence, the required explicit formula of the given situation,

Total number of 7-poker cards are 52P7 = 133784560
A) Determine the probabilities of Seven-card straight
probability of seven-card straight = 0.00031
B) Determine the probability of four cards of one rank and three of a different rank
P( four cards of one rank and three of different rank ) = 0.0017
C) Determine probability of three cards of one rank and two cards of each two different ranks
P( three cards one rank and two cards of two different ranks ) = 0.31
D) Determine probability of two cards of each of three different ranks and a card of a fourth rank
P ( two cards of each of three different ranks and a card of fourth rank ) = 0.00018
