Remember, probability is;
2. Find probability 1
favorable out comes; diamond = 5
total outcomes; total cards = 15
probability is;
Simplified;
3. Finding probability 2
If the last card drawn was a diamond then the new numbers will be
favorable outcomes; 4
total outcomes; 14
Probability is;
Simplified;
4. Total probability
Now, one has to multiply the first probability by the second probability to find the probability of the event;
=
= 0.095238

We have , Garne Problem med . A rover needs to travel mile to reach its destination traveled mile. a rover needs to travel 5/8 mile to reach its destination it has already travel 3/8 miles . We need to find that how much farther does the rover need to travel , Let's do it step by step:
First , rover has already traveled 3/8 miles , Let total distance to be traveled by rover is D :
⇒ , where d is distance left to cover .
Now, rover need to travel 5/8 miles more to reach destination :
⇒ , where d is distance left to cover , So
⇒
⇒
