Question

a bag a contains 4 white and 3 black balls another bag B contains 5 white and 2 black balls A ball is drawn from each bag the probability of getting balls of different colours is

Answer 1

Answer:

for 1st bag white ball=4/7,black =3/7,for 2nd bag white ball =5/7,black ball=2/7

Step-by-step explanation:

1st step write the sample space of both the bags

2nd then name each event

formula for probability n[a]/n[s]

Answer 2

$\sf\underline{Step-by-step \: explanation}$

------Sample space------

White , black ; Black , black ; White , white ;

Black , white.

---------------------------------------------------------

Probability= $\frac{No. \: of \: events}{Total \: events}$

Probability = $\dfrac{2}{4}$

Cancellation...

1/2

Hence, the required answer is,

$\huge{1/2}$
