<u>Answer</u>

2,737,152a⁵b⁵

<u>Explanation</u>

(2a - 3b)¹⁰ = (2a)¹⁰ - 10(2a)⁹(3b) + 47(2a)⁸(3b)² - 144(2a)⁷(3b)³ - 212(2a)⁶(3b)⁴ + 352(2a)⁵(3b)⁵

The 6th term in this expression is 352(2a)⁵(3b)⁵

352(2a)⁵(3b)⁵ = 352 × 2⁵a⁵ × 3⁵b⁵

= 352 × 32 ×243 ×a⁵b⁵

= 2,737,152a⁵b⁵

RideAnS [48]

Answer:

24/91

Step-by-step explanation:

6 red socks and 8 black = 14 socks

P( red) = red/total = 6/14 = 3/7

Keep the red sock

5 red socks and 8 black = 13 socks

P(black) = black / total = 8/13

P(red, black, keeping the sock) = 3/7 * 8/13 = 24/91
