Answer:
10/13
Step-by-step explanation:
The probability of the occurrence of an event is ration of the number of possible outcome to the number of total outcome.
Where items are picked without replacements, we have to note the reduction in the number of possible outcome and total number of outcome.
Given that there are 4 pennies, 3 nickels and 6 dimes
The probability of picking a penny or a dime
= 4/(4 + 3 + 6) + 6/(4 + 3 + 6)
= 4/13 + 6/13
= 10/13
