To find the probability of randomly selecting a penny or a half-dollar from the bag, we first need to find the total number of pennies and half-dollars in the bag.

Total number of pennies = 16
Total number of half-dollars = 7

Total number of pennies and half-dollars = 16 + 7 = 23

Total number of coins in the bag = 9 + 16 + 10 + 8 + 7 = 50

Probability of randomly selecting a penny or a half-dollar = (Number of pennies + Number of half-dollars) / Total number of coins
= 23 / 50
= 0.46 or 46%

Therefore, the probability of randomly selecting a penny or a half-dollar from the bag is 0.46 or 46%.
