Jim picked a card from a standard deck, looked at it, and then put it back. he then picked a second card. what is the probability that jim picked a heart or an ace on either pick?

one over fifty two

two over fifty two

sixteen over fifty two

seventeen over fifty two

sixteen over fifty two

Step-by-step explanation:

Jim picked a card from a standard deck, looked at it, and then put it back.

He then picked a second card.

What is the probability that Jim picked a heart or an ace on either pick.

number of hearts or aces=16  

(13 hearts and 4 aces but heart also has one ace so total=13+4-1=16)

Total number of cards=52

Hence, P(Jim picked a heart or an ace on either pick)

            = 16/52

Hence, correct option is:

sixteen over fifty two

answer: 25.4 units

step-by-step explanation: radius = 12.7 units

diameter = twice the radius

diameter = 12.7 x 2

= 25.4
