Answer 1

Answer:

please mark as brainliest

Step-by-step explanation:

total probability of black and white balls =6+4

=10

probability of getting white ball=4/10

=2/5

Answer 2

Answer:

let S be the sample space

S={B1,B2,B3,B4,B5,B6,W1,W2,W3,W4}

N(S)=10

LET A BE THE EVENT THAT A WHITE BALL IS PICKED

A={W1,W2,W3,W4}

N(A)=4

BY DEFINITION OF PROBABILITY

P(A)=N(A)/N(S)

=4/10

=2/5

THEREFORE THE BOOK PROBABILITY OF GETTING A WHITE BALL IS 2/5
