C ≈ 11.71 cm
Step-by-step explanation:
using the ratio arc AC : circumference C = angle at centre of sector : 360°
=
, that is
=
( cross- multiply )
123 × C = 4 × 360 = 1440 ( divide both sides by 123 )
C = ≈ 11.71 cm ( to the nearest hundredth )
Answer:
Step-by-step explanation:
Sample Space for the Cube, A={1,2,3,4,5,6}
n(A)=6
Even Numbers in A={2,4,6}
Sample Space for the Cards, B={1,2,3,4,5}
n(B)=5
Even numbers in the card,B= {2,4}
The two events are INDEPENDENT Events as the outcome of the cube does not affect the card picked, therefore:
P(A and B)=P(A) X P(B)
=
=
