Answer :
The change of occurring an event is known as Probability.
You can solve probability questions by following some formulas
Conditional probability- P ( A l B ) = P ( A ^ B ) / P (B)
Bayes - P (A l B) = P (B l A)
P (A) / P (B)
Complementary- P(A^c) + P (A) = 1
Answer:
x=2√5/5
x=-2√5/5
Step-by-step explanation:
13√(2√5/5)^2-(2√5/5)^4+9√(2√5/5)^2+(2√5/5)^4=16
13√(4×5/25)-(16×25/625)+9√(4×5/25)+(16×25/625)
13√(4/5)-(16/25)+9√(4/5)+(16/25)
13√(4/25)+9√(36/25)
13×2/5+9×6/5
26/5+54/5
16=16 (proven)
