How to calculate a probability
Lelu [443]
Probability is calculated by comparing the odds to a certain event occurring to the number of possible events.

P=\frac{possibility-of-an-event-occuring}{number-of-total-outcomes}

For example, take a six-sided dice number 1-6 on each side. The probability of rolling a 4 would be1 in 6 or 1/6. This is because of the six possible outcomes, rolling a 4 is only one of them.

P(4)=1/6

Now take the same dice. The probability of rolling an even number is 3/6. To see why, lets look at the total possible outcomes:

1
2
3
4
5
6

Of the 6 possibilities, 3 are even numbers.

P(even)=3/6 or 1/2

jennifer bikes 7 miles south and then turns to bike 13 miles east how far away is she from where she started?
Marina CMI [18]

Answer:

She is about 14.765 miles (\sqrt{218} miles) from where she started

Step-by-step explanation:

There is a relation between the three sides of the right triangle

  • The side opposite to the right angle is called hypotenuse and it is the longest side
  • The other two sides called legs of the right angle
  • The relation between them is: (hypotenuse)² = (leg1)² + (leg2)²

∵ Jennifer bikes 7 miles south

∵ She turns to bike 13 miles east

∵ South and East are perpendicular

→ That means the distance from her start point to end point represents

   a hypotenuse of a right triangle, whose legs are 7 and 13

∴  (hypotenuse)² =  (leg1)² + (leg2)², where

  • hypotenuse is the distance between her start and end points
  • leg1 is her distance in south direction
  • leg2 is her distance in east direction

∵ Leg1 = 7 miles

∵ leg 2 = 13 miles

∴ (hypotenuse)² =  (7)² + (13)²

∴ (hypotenuse)² = 49 + 169

∴ (hypotenuse)² = 218

→ Take √  for both sides

∴ hypotenuse = \sqrt{218}

∴ hypotenuse ≅ 14.76482306

∴ She is about 14.765 miles (\sqrt{218} miles) from where she started.
