Jerry has set aside a certain amount of money to download applications for his new smartphone. The number of applications he can afford to download is inversely proportional to the cost of each download. With his money, he can afford 12 applications that cost 2 dollars each. How many applications can he afford to download if he finds less expensive applications that cost only 1.50 dollars each?

Final answer is 5/6.

Step-by-step explanation:

Given that you roll a standard six sided number cube.

Now we need to find about what is the probability of rolling a prime number or a number greater than 3.

Total numbers in a six sided cube = 6 {1,2,3,4,5,6}

Total prime or numbers greater than 3 in a six sided cube = 5 {2,3,4,5,6}

Hence probability of rolling a prime number or a number greater than 3 = [favorable number of events] / [total possible events] = 5/6

Hence final answer is 5/6.
