Step-by-step explanation:
Using the sum/ difference → product formula
cos x - cos y = - 2sin( )sin ( )
sin x - sin y = 2cos ( )sin ( )
Given
(cosA - cosB)² + (sinA - sinB )²
= [ - 2sin()sin( ) ]² + [ 2cos( )sin( ) ]²
= 4sin² ( )sin² ( ) + 4cos² ( )sin² ( )
= 4sin² ( )[ sin² ( ) + cos² ( ) ← sin²x + cos²x = 1
= 4sin² ( ) × 1
= 4sin² ( ) = right side ⇒ proven
Answer:
25 times
Explanation:
Blue Marvels: 3
Red Marvels: 5
Total Marvels: 5 + 3 = 8 marvels
Probability: favorable outcomes/total outcomes
Probability - red marble = 5/8
After Doing 40 times:
= 5/8 × 40
= 25
