Answer:
Step-by-step explanation:Knowing that
There are 26 black cards and 26 red ones. Face card consists of jack (J), queen (Q), king (K). There are (26-6)=20 non face red cards. “Either ... or ...” here means bundle of both kinds of cards.
So, there are (26+20)=46 expected cards.
If you also ask for the probability, so the probability of the question asking above is equal to
23/26
Considering that the data is only noted and not changed, this is an example of an observational study.
<h3>What are observational and experimental studies?</h3>
- Experimental study: In an experimental study, there is an intervention in a sample, and it's effect is studied.
- Observational study: In an observational study, the sample is just analyzed, without any intervention.
In this problem, the data, which is the number of miles traveled, is only analyzed, no interventions are made, hence this is an example of an observational study.
