With a typical 52-card deck that has 4 jacks, Margaret is playing a game. The game is initiated by the first player to choose a jack. When choosing first, Margaret's probability of selecting Jack is 1/13.
The same will occur since probability will be determined using the formula necessary outcome divided by total outcome.
Here, the total number of cards in the deck (total outcome) equals 52.
Given that Margaret can select any of the four jacks, the necessary result (number of jacks) is 4.
Probability is 4/52, or 1 by 13, which is the required probability for the question.

The mass of hydrogen in 57.010 g ammonium hydrogen phosphate, (NH₄)H₂PO₄ is 2.97 g
<h3>Determination of mass of 1 mole of (NH₄)H₂PO₄ </h3>
1 mole of (NH₄)H₂PO₄ = 14 + (4×1) + (2×1) + 31 + (16×4) = 115 g
<h3>Determination of the mass of H in 1 mole of (NH₄)H₂PO₄ </h3>
Mass of H = 6H = 6 × 1 = 6 g
<h3>Determination of the mass of H in 57.010 g of (NH₄)H₂PO₄ </h3>
115 g of (NH₄)H₂PO₄ contains 6 g of H.
Therefore,
57.010 g of (NH₄)H₂PO₄ will contain = (57.010 × 6) / 115 = 2.97 g of H
Thus, 2.97 g of Hydrogen, H is present in 57.010 g of (NH₄)H₂PO₄

A black and white scene showing men on horseback and men standing in a field. this print, created by picasso, displays a bold, highly contrasting design, which is characteristic of wood engraving.
Engraving begins by using a sharp, hand-held cutting device called a chisel to draw a design directly onto a metal plate. The tip of the chisel is sharp and pointed. The technique of wood engraving has been used for centuries to reproduce drawings and paintings.
This allowed more people to own or see the artwork of artists who would otherwise only have the original, eliminating the possibility of additional "copies" of their own images. By the 19th century, it was largely abandoned in favor of etching.
Picasso's use of chisels was always unorthodox, but he and other artists used chisels to create sharp, crisp lines on his plates that were etched into the printed image. converted evenly.
The correct answer is option B.
