Answer:
Step-by-step explanation:
"mutually exclusive" means "cannot happen at the same time." There's no "union" (no A ∩ B). The probability of this "union" is zero.
A1 is the first term, in this case, A1 is 1
R is the ratio between adjacent numbers, in this case, R=3 because 3/1=3, 9/3=3, 27/9=3, 81/27=3
The expanded form of a number involves rewriting the number
The expanded form of 239238 is 13291 * 3 * 3 * 2
<h3>How to write the number in an expanded form</h3>
The number is given as: 239238
Express as a product of 2
239238 = 119619 * 2
Express as a product of 3
239238 = 39873 * 3 * 2
Further, expand
239238 = 13291 * 3 * 3 * 2
The number cannot be further expanded.
Hence, the expanded form of 239238 is 13291 * 3 * 3 * 2
