Probability is such a native part of your life that you rarely think about it. Though, every time you use a word like "might", "may," "undoubtedly", "without fail," or "maybe", you can see and even a probability that an event will occur. Find the Probability of Getting: 1. Three Heads 2. Three Tails 3. Two Heads 4. Two Tails When you toss Four Coins. Try tossing four coins 16 times and writing down the outcomes. Are the probabilities roughly equal as you calculated in step 2? Try tossing four coins 24 times and writing down the outcomes. Are the probabilities any closer?

Step-by-step explanation:
Going from home to school-
Constant speed = 2.5km/h
Distance = 6km
Time taken = 6/2.5
= 2.4 hours
Going from school to home-
Constant speed = 4km/h
Distance = 6km
Time taken = 6/4
= 1.5 hours
Total time is taken in traveling = 3.9 hours
Total distance = 12km
Average speed of round-trip = 12/3.9
= 3.08 hoursThe essential requirement of memory management is to provide ways to dynamically allocate portions of memory to programs at their request, and free it for reuse when no longer needed. This is critical to any advanced computer system where more than a single process might be underway at any time.Let y and z be 3u and 7u
∠x=∠z (Alternate angles)
∠x+∠y=180
