Problem: Using the formula fraction of the circle x circumference = arc length.Find length of minor arc AB.

Mathematics

Answer: The length of minor arc AB = 12.56 units.

Step-by-step explanation: The circle x has its circumference given as 2Pi x r.

A fraction of the circle is given as O/360,

Where O is the angle subtended at the center of the arc AB.

The length of an arc can be calculated by the formula;

Length of arc = O/360 x (2Pi x r)

Length of arc = 60/360 x (2 x 3.14 x 12)

Length of arc = 1/6 x (6.28 x 12)

Length of arc = 12.56 units.

Therefore the length of minor arc AB = 12.56 units

7. A crate of soft drinks contains 9 bottles of coke, 6 bottles of pepsi and 4 bottles of limca. Ademola picks one bottle of sof
Mekhanik [1.2K]

The probability that the events (a) they both picked Limca = 0.04, (b) Ademola only picked Pepsi = 0.32, (c) They both picked the same brand = 0.33 (d) They picked different brand=0.67.

<h3>What is probability?</h3>

Probability is the fraction of the required outcome event divided by the number of possible outcomes of events.

Total possible outcome of the event of picking drinks contained in the crate = 19

Hence, we can compute the following as follows;

(a) The probability they both picked Limca = (4/19)×(3/18)

Limca = 12/342

Limca = 0.04

(b) The probability Ademola only picked pepsi = 6/19

pepsi = 0.32

(c) The probability they both picked the same brand = (9/19)×(8/18)+(6/19)×(5/18)+(4/19)×(3/18)

=(72+29+12)/342

= 114/342

= 0.33

(d) The probability they picked different brand = (9/19)×(6/18)+(9/19)×(4/18)+(6/19)×(9/18)+(6/19)×(4/18)+(4/19)×(9/18)+(4/19)×(6/18)

The probability they picked different brand = (54+36+54+24+36+24)/342

The probability they picked different brand = 228/332

The probability they picked different brand = 0.67

Therefore, the probability for events (a) is 0.04, (b) is 0.32, (c) is 0.33 and (d) is 0.67.
